Can you conceal a Cable or Cord Reels in a acoustical drop ceiling?
We can not recommend concealing any of our of Cable or Cord reels in an acoustical drop ceiling. For a couple of reasons; first NEC® 400.8 generally forbids flexible cords or cables being located above suspended or drop ceilings. Flexible cords and cables cannot be concealed in the ceiling. The cable passing through the acoustical tile material may cause vibration in the drop ceiling system if the cable isn't retracted correctly, the cable or box could hit the acoustical drop ceiling causing tiles to fall.
What is the reason for not installing a cable reel higher than 16 feet?
Beyond 16 feet from the floor there becomes a concern for the ability of the reel's retraction spring to retract under the weight of the cord and whatever may be attached to/ plugged into it.
Do you sell cord reels with no ends?
Yes, the BRY501xxxxW series of weatherproof cord reels are sold with no ends.
I need a cord reel with constant tension. Can you help me?
Yes, on our series of weatherproof cord reels (ie; BRY501232W) the ratchet mechanism can be disengaged in the field for constant tension. The reels are shipped with instructions on how to do it.
How do I adjust the tension of your cord reels?
Adjusting the tension on our weatherproof and industrial cords can be done by adding wraps (increasing tension) or removing raps (decreasing tension) from the spool. Please exercise extreme caution because too much tension could cause injury or damage the spring. The reels are shipped with instructions on how to do it.
Can you use Cam-Type Device Connectors on motors?
Cam-Type Device Connectors can not be used with motor loads, they do not have UL or CSA horse power ratings.
What is the frequency rating of the Cam-Type Devices?
The maximum rating of the Cam-Type Devices is 600VAC/ 250VDC for either 300 or 400 Amps at 60Hz frequency.

The Cam-Type Devices are not UL listed for welding cable. They are list for Type SC, SCE, SCT, PPC and Type W, PPE cable type only.
What type of cable can be used with Cam-Type Device Connectors?
The Cam-Type plug and connectors are UL listed for Type SC, SCE, SCT, PPC and Type W, PPE cable.
Can you use DLO cable (UL RHH/RHW - 2) on Cam-Type plugs and connectors?
Our Cam-Type plug and connectors are not designed to be used with DLO (UL RHH/RHW-2) cable. We do not have listing for use with this cable so the customer is doing it at their own risk. Single pole devices are listed to be used with 90 Degree C. Power cable types SC, SCE, SCT, PPE, PPC or W [.460"(11.7mm) - 1.020"(25.99mm)].
What type of environmental rating does the GFP15A have?
GFP15A meets UL & CSA watertight requirements, adhesive bonded.
How often should I test my GFCI receptacles?
Per UL, it is recommended that you perform the self diagnostic test, push the TEST button then RESET button on the face of the receptacle, once a month.
What is the torque requirements for terminal screws on GFCI receptacles?
The terminal screw torque is typically 14 to 16 in-lbs. But always reference the supplied installation instructions.
What is the noise immunity level in UL943 for new Ground Fault Products?
What is the noise immunity level in UL943 for old Ground Fault Products?
The old noise immunity level was to have proper Ground Fault Products operation with a continuous un-modulated sine-wave, measured at 0.5Vrms across a 51 ohm load, within a 10 to 450Mhz frequency spectrum.
Why won't Ground Fault Products function correctly if connected to the load side of an inverter that produces a square sine wave?
The key factors are the slow ramping start up, inconsistent voltage and low frequencies that could cause it not to function correctly or damage the product.
Where is the best place to use my GFCI portable? Plug it into the wall with the extension into the portable or plug it into the extension cord and plug my drill into the portable?
Plug your portable GFCI into the wall then plug your extension cord into the portable and plug your drill into the extension cord, this will not only protect the person while using the drill but it will also provide protection when handling the extension cord.
I was told that if I load one GFCI receptacle off another GFCI receptacles they would cancel each other out. Is this true?
No; all GFCI receptacles are manufactured to UL 943 Class A, 4-6 mA. This means if the circuit is subjected to a ground fault, the receptacle with the lowest trip level will most likely trip first.
Would I have a problem plugging a GFCI plug into a GFCI receptacle?
No; all GFCI receptacles and plugs are manufactures to UL 943 Class A, 4-6 mA. This means if the circuit is subject ground fault, the device with the lowest trip level will most likely trip first.
Does Bryant do any testing for energy consumption and stand-by loads for various Ground Fault Products receptacles?
At this time Bryant does not perform tests in terms of standby loads or energy consumption in Ground Fault Products. Currently manufactured GFCI receptacles are not designed to go into a power consumption mode.
Will your GFCI devices work on 120V @ 50Hz?
No, Bryant GFCI products should not be used on 50Hz.
Does Bryant have a split circuit Ground Fault receptacles available?
Bryant does not have a split circuit ground fault receptacles available at this time .
What is the vibration/shock GFCI receptacles will withstand?
Please note, there are no specific vibration test requirements for ground fault receptacles. However, we have experience based on generator and mobile power applications. The unit must not trip during this test sequence. Vibration condition: Acceleration 29.4 m/s2; 3G peak Frequency: 40 to 400 Hz Sweep Time: 1 hour Duration: 300 hours Direction: X, Y & Z
Can you please tell me if there is a problem using a ground fault receptacle on an arc fault circuit breaker?
We are not aware of any issues that would prevent a GFCI receptacle from being used on a branch circuit protected by an AFCI circuit breaker.
Do Bryant GFCI receptacles have a horsepower rating?
Currently our GFCI receptacles do not have a horsepower rating.
Are ducts and plenums considered the same?
Yes. The definition of plenum in the NEC® Article 100 is "A compartment or chamber to which one or more air ducts are connected and that forms part of the air distribution system". Ducts and plenums are equally addressed by NEC® 300.22(b).
What is the equation to figure out the line of sight for the MSU2000C when used in a hallway application?
Use the following equation to figure out the line of sight for the MSU2000C when used in a hallway application Width x Height = X , 3200 / X = Line of Sight, Line of Sight x 2 = Total Sight Of MSU2000C
Do you carry cages to protect your occupancy motion sensors?
Yes, contact Technical Service for information.
Are Bryant MSAR add-a-relays and MSCU control units plenum rated?
Yes, the MSAR (add-a-relay) and MSCU control units are plenum rated.
Do you have a 3-way line voltage motion wall switches?
No and Yes. We do not have a motion switch that is wired like a conventional 3-way switch. You use two standard line voltage motion switches. You wire the line and load to each motion switch. The first switch to see motion will turn the load on, the last switch to see motion will shut it off. You can't exceed the rating of one switch.
We have a problem with the contacts on our power packs sticking. What could be the cause?
This occurs when there is too much inrush current on the circuit. This may be caused by; to many multiple CFL lights on the circuit, how far the circuit is away from the main feed, how much resistance is on the wire, etc. You could try is to split up the circuit evenly with 2 control units to distribute the load more evenly.
A low voltage ceiling sensor was temporarily installed for 40 days. It is now being moved to a new location. Can the learned settings be erased and started over?
Yes. Toggle dip switch A4 to on for two seconds, then back to off. The learning process starts all over again.
If I set the green adjustment knob (ultrasonic sensitivity) of a dual technology low voltage sensor to zero, can the sensor operate as a passive infrared sensor?
Yes. Set the dip switch A2 to High Sensitivity (ON), B4 to Manual Sensitivity (ON) and set the green knob to zero. The dual tech is now a PIR sensor only. Same can be done for ultrasonic only operation.
Why do the MSD500C, MSD1000C, MSU500C, & MSU1000C have 180 degree coverage patterns?
This is done to maximize performance in smaller spaces like private offices and conference rooms. The 180° coverage allows you to position the sensor close to the entry while eliminating false-ons from hallway traffic.
What is the longest distance a sensor can be from the control unit?
It is recommended to not exceed 250 feet from the control unit to the farthest sensor, using 18-22 AWG wire.
Can the learned settings on the adaptive wall switch sensors (MSD1000xx & MSU400xx) be reset?
Yes, toggle dip switch number 8 (top dip switch) from off to on, wait two seconds, then toggle back to the off position. This will restore the original factory settings.
Do Adaptive Technolog sensors interfere with Interactive Whiteboards?
There are four main technologies that interactive whiteboards use for marker tracking; IR scan, ultrasonic, resistive touch and electromagnetic touch. The only technology that will have interference issues is ultrasonic sensing. Ultrasonic sensing boards are predominantly made by mimio, Panasonic, and Hitachi. The market share for ultrasonic boards is small. The most common whiteboard technology used today is electromagnetic sensing and this has no interference issues with ultrasonic sensing. This is what market leaders SMART and Promethean use.
Do Adaptive Technology sensors interfere with Hearing Aids?
There should be no issue with most modern hearing aids. Previous issues in the 80s-90s resulted from improper hearing aid designs. A NEMA-sponsored study, conducted by David F. Henry, PhD and Barak Dar, “Effects of Ultrasonic Sensors on Hearing Aids” (February 2006), concluded: “After assessing 23 hearing aids representing the digital products of all major hearing aid manufacturers, just two hearing instruments were severely affected by ultrasonic occupancy sensor devices. One device, the ImpaCt DSR675 manufactured by AVR Son ovation, has not been in production for over four years. Newer hearing instruments from this manufacturer have exhibited no interference when exposed to the ultrasonic occupancy sensor signals. The second device, the Bravo, manufactured by Wide, is still in production. However, the manufacturer reports that they have developed a modification that can be made to the instrument that greatly reduces the susceptibility of the instrument to ultrasonic occupancy sensor signals.”
Do Adaptive Technology line voltage sensors, control units and add-a relays employ "zero arc point " switching?
All Adaptive technology line voltage sensors (ceiling and wall switch), control units and add-a relays employ "zero arc point " switching, with the exception of the "incandescent only" residential wall switch sensors (RMS100xx, RMS101xx, RMS120xx, RMS121xx).
Can sensors see motion through glass walls or windows?
No, neither infrared nor ultrasonic technologies can "see" motion through glass walls or windows.
Do the adjustment knobs move during self-adjusting?
No, just the values change in the sensor's microprocessor.
Why have the adjustment knobs at all?
They are factory set and represent the starting point for the sensor to adapt from. The knobs still exist so that the sensor can be manually set up for customer specific applications. When the application requires a non-adaptive sensor, dip switches are provided to override the adaptive feature. (Refer to sensor installation instructions for details.)
What are factory timer settings?
Adaptive Technology Wall Switches; 15 minutes (intial setting). Adaptive Technology Low Voltage Ceiling & Wall Sensors; 8 minutes (intial setting).
What is a false-on?
A false-on is when the lights turn on when there are no occupants in the intended area of coverage. False-ons typically occur when the sensor detects a hallway passerby and turns the lights on. The lights then stay on for an entire timer cycle.
Do we have a solution for false-ons?
Choosing the correct technology sensor, with the correct coverage pattern, and placing/aiming it correctly will inherently reduce false-ons. Adaptive Technology and PIR lens masking, would also help.
How does the sensor adapt to false-ons?
If a minor motion signal is received and no major motion signal is seen within 5 seconds (passerby but no room entry, typically) the sensitivity of the dominant technology (the technology which sensed the passerby first) is reduced by 6%.
Do Adaptive Technology sensors, "fail safe" or fail with the lights on?
No manufacture can guarantee that their sensor will fail to an "on" state. There are too many variables and potential failure scenarios to guarantee that a product will fail with the lights on.
Do Adaptive Technology sensors interfere with Pacemakers?
The power levels and transducer style (piezoelectric) we use have no known issues with pace makers. The only precautions we’ve found regarding pacemakers and ultrasonic is for ultrasound imaging machines or certain ultrasonic dental equipment. Both use higher power transmitters and are operated in close proximity to the body.
Why are Dual Technology sensors superior to single technology sensors?
Infrared sensors are more immune to false-turn ons, but lack sensitivity to small motions. Ultrasonic sensors are noted for their sensitivity to small motions but can be susceptible to air currents from climate control systems which can cause false-ons, typically at night. By combining the two sensing technologies, both can be used at their strengths; infrared to keep the lights off when unoccupied, ultrasonic to keep the lights on when the room is occupied. Also, ultrasonic is more sensitive to approaching motions, while infrared is more sensitive to lateral motions. Combining the two provides better detection in all directions.
If the timer is accidentally left in the test mode (8 seconds for low voltage ceiling & wall sensors, and 10 seconds for wall switches), what does the sensor do?
The Adaptive Technology sensors will exit the test mode automatically after 1 hour.
How are the sensors put into "test mode"?
For the adaptive wall switches, MSD1000xx & MSU400xx, press and hold front press switch till lights turn off and come back on, then release button. The sensor is now set to a 10 second test time delay. For Adaptive Technology low voltage ceiling, turn the time delay knob (the black knob located behind the lens retainer) fully clockwise, then fully counterclockwise. The sensor is now set to a 8 second time delay.
Does Adaptive Technology address ultrasonic false-ons from air currents?
Yes. Activity spikes from air currents are continually analyzed and evaluated. The sensor automatically adjusts it's turn on threshold to prevent spikes from turning on the lights. If, during the occurrence of air conditioning spikes, occupancy occurs, the sensor recognizes the difference between the two sources and turns the lights on.
If I get a "false-off" occurrence (lights turn off when area is occupied) what will the sensor do?
Adaptive Technology wall switches and ceiling sensors consider false-off as a major sensor performance error. The wall switch will increase the time delay to eliminate future false-offs. The ceiling sensors will increase both the time delay and the ultrasonic sensitivity by 6%.
Upon power up, how long does the sensor need to start working?
Typically, two or three minutes. Lights are on during this time.
What is the warranty on Occupancy Sensors products?
We have a five year limited warranty on the Occupancy Sensor product line.
Are Adaptive Technology sensors compatible with all ballasts?
Yes, they are compatible with all ballasts but, program start ballasts are recommended for lamp longevity.
Why are Adaptive Technology sensors superior to other occupancy sensors?
Install it and forget it. Adaptive technology sensors automatically adjust for sensitivity and time. It takes about 3-5 days of use for the sensors to learn the environment.
Why do sensors need to adjust?
Environmental conditions constantly change; climate control systems turn on and off, background temperatures change with the seasons, and office furniture density and layout change over time. For proper operation, the sensor should be adjusted each time one of these changes occur. Adaptive Technology eliminates the ongoing maintenance required to have sensors operate reliably in the changing office environment.
What is inside Adaptive Technology sensors that allows them to learn?
The Adaptive Technology chip; a small internal microprocessor that combines digital signal processing, control logic and adaptive algorithms (formulas).
Are Adaptive Technology sensors reliable? Have they been tested to confirm performance claims?
Units have been in production since 1997 and reliability has been excellent.
Is there an easy way to tell what is the mating plug is for your 70520FR locking receptacle?
There is a suffix system or the Bryant NEMA rated locking devices . Receptacles end with an FR suffix, example- 70520FR. Flanged receptacles end with ER, example- 70520ER, Connector Bodies end with NC, example- 70520NC. Plugs end with NP, example- 70520NP. Flanged inlets end with MB, example- 70520MB. In this example all these devices are 20amp 125 volts.
Do you have Hospital Grade Locking devices?
No one sells Hospital Grade Locking devices. UL does not have category for hospital grade locking devices, only for 15A and 20A straight blade devices.
Are NEMA® configurations require to be marked with HP rating?
Horsepower ratings for NEMA Locking devices plugs and receptacles are generic. They are all equal and cannot be greater or less than any other. Because all NEMA plugs and receptacles are rated HP rated, that marking is optional as defined in the UL Standard for Attachment Plugs and Receptacles, UL498 table 163.1 (All plugs - Exception No. 2). The UL Guide card for attachment plugs specifies the HP rating for all NEMA configuration. This is usually the only documentation required for inspectors at time of installation.
I can't find a two gang wall plate for my Locking (1.56" dia.) receptacles.
You can not use a two gang box for two locking receptacles with a 1.56" face diameter, you will have to install them in a three gang box. If you try to install them in a two gang box you will only be able to use one receptacle at a time. The receptacles will be 1.81" on center. The body diameter of our locking plugs are 2.13". We do offer a three gang plate for two receptacles in stainless steel, the center gang is blank. The 3-gang plate catalog number is SS320.
I can not mount this 26522 (60A flanged inlet) on to a 26401 box. What am I doing wrong?
The 26401 box is designed to be used with an adapter (either 26402 or 26404) for the 60A receptacles (IE; 26401), not the inlet. At this time we do not have a box or cover that a 60A flanged inlets can mount into. They can only be panel mounted.
I can't find weatherproof boots in your catalog for the 26519 and 26516 plug and connectors.
I'm sorry but we do not have weatherproof boots for out 60A Power Interruping plugs and connectors. If you need a plug and connector that is weatherproof you can use one of our Pin & Sleeve products. See our on line catalog or contact Technical Service for product information.
Your 26410 that I have will not accept your 26401 back box. Why?
Our 60A power interrupting receptacles; 26520, 26410 and 26420, will not mount directly to the 26401 back box. One of our adapters are required. Either the 26402 (straight adapter) or 26404 (angled adapter).
Do you sell a receptacle with a NEMA L14-50R configuration?
No one manufactures a NEMA locking configuration L14-50R. NEMA locking configurations only go up to 30A. L14-50R indicates a 3-pole 4-wire, 125/250V, 50A locking receptacle. Our CS6369A has those ratings. The mating plug is CS6365.
Do you sell a plug with a NEMA L21-50P configuration?
No one manufactures a NEMA locking configuration L21-50P, locking configurations only go up to 30A. L21-50P indicates a 4-pole 5-wire, 3 phase 120/208V, 50A locking plug is needed. We have to recommend going to our 60A Pin & Sleeve line. Our 560P9W has a 4-pole 5-wire, 3 phase 120/208V, 60A rating. The mating plug is 560P9W.
I have your CS6369A. Is the center pin the ground?
No, the center pin on our CS6369A receptacle (as with all 50A locking receptacles with the center pin) is a rejection pin. It is not a ground or current carrying contact. The metal can on the side of the CS6369A is the ground contact. The rejection pin is so the dual rated configurations (50A 600VAC and 250V DC) are not interchangeable.
Does your Bryant 664X33D & 664X63D switch meet NEMA KS-1?
No. NEMA KS-1 would be a UL98-type Enclosed Switch (colloquially a "Safety Switch"). Ours is a UL508 Manual Motor Controller. However, it is "Also Suitable as A Disconnect" which means that per NEC® 430.109(A)(6), it's equivalent on a motor branch circuit. (Can't be used on a feeder circuit, however.)
Can I purchase replacement parts for your 664X33D disconnect?
Yes. We offer the following; Replacement 3 pole switch- 66033D. Replacement handle kit- 6610MK. Aux. contact (NO/NC)- 660AC. Replacement mounting feet- 664XFT. Replacemetn neutral buss- 6603N.
Can I purchase replacement parts for your 664X63D disconnect?
Yes. We offer the following; Replacement 3 pole switch- 66063D. Replacement handle kit- 6610MK. Aux. contact (NO/NC)- 660AC. Replacement mounting feet- 664XFT. Replacemetn neutral buss- 6603N.
Can I purchase the replacement switch for your 30323D
Yes; the replacement switch is 30003DS.
Can your 3R motor controller disconnect be locked in the on and off position?
No, our 3R motor controller disconnects be can only be locked in the off positions.
Do you have an enclosures or boxes for your 40A, 50A and 85A manual motor controllers?
At this time we do not offer enclosures for our 40A, 50A and 85A manual motor controllers. These controllers are primarily used by OEMs who panel mount them into their products.
Does UL or NEC® specify the ground up or ground down on straight blade receptacles?
The answer is no. The position is a matter of choice or local code enforcement. If the receptacle is mounted vertically, a growing number of users prefer to locate the ground up, and if mounted horizontally, the ground slot is oriented to the left. The rationale is that a metallic object falling on a partially inserted plug will be more likely to contact the ground blade of a 3-wire plug rather than the hot blade. If mounted horizontally, the falling object would contact either the neutral and/or ground blades.
Do Bryant receptacles and plugs meet NEMA WD6?
Yes, NEMA WD6 is the configuration standard for straight blade and locking devices. The old designation for devices was, Straight Blade- WD1 and Locking- WD5. Both have now been grouped together into WD6. WD1 is now a color standard.
What is the test UL 4X test; the amount of water pressure and how far away is the nozzle?
A sample enclosure is mounted in it's intended manner. The enclosure, including external operating mechanism, is subjected to a stream of water from the hose having 1 inch nozzle delivering 65 gallons of water per minute. The water is directed at the joints of the enclosure from a distance of 12-10 ft and the water stream was moved along the joints or surface at the rate of 48 square feet The duration of the test is 5 minutes.
What is the letter designation on the end of a Federal Specification number mean?
It's the edition designation for any given Federal Specification. When a new edition is issued by the US Department of Defense, prior editions are rendered null and void. The latest edition of the general specification for plugs, receptacles and connectors is WC596G and for switches is WS896F.
What is the web site for CSA?
What is the web site for UL?
Please advise the CSA standard number under which the line of Wire Management Product grips is listed.
The CSA standard is C22.2 No. 18.3-04. It is a tri-national standard used in Canada, USA and Mexico.
I have a lot of old non-NEMA devices that are dual rated. How come they are in the catalog but not dual rated anymore?
The 600 volt rating on the devices has been removed. If the application calls for this rating, you can no longer use these devices. New NEMA rated devices with the proper rating should be purchased.
What is the definition of terms used to classify wiring devices such as duplex receptacles?" ("Commercial Grade", "Industrial Grade", "Specification Grade", "Hospital Grade".)
Of the terms used all are marketing descriptions except "Hospital Grade." "Hospital Grade" plugs and receptacles undergo a more stringent battery of UL administered performance tests to earn a "Hospital Grade” designation. Commercial/ Specification/ Industrial are terms we use to stratify our product offering, Good-Better-Best strategy. These terms mean different things to different manufacturers and there is no industry requirement that these need to meet. At Bryant we've always been most put off by the "Specification Grade" term. As long as the correct receptacle is chosen for the given application it should be specified! So all of our duplexes carry the "Specification Grade" description. That leaves "Commercial Grade" and "Industrial Grade." It is our feeling that people intuitively know an industrial application when they see it. If you have to buy parts for an industrial job you're thinking: "I need one seriously tough stuff for this job." The "Commercial and Industrial grade receptacles are both very well constructed. You need to ask, "Do I need a 80 ton, Tri-Axle truck or will my pick up truck be enough truck for the job?" Do I need all brass parts used with reinforced nylon or will steel do? As for Bryant receptacles and switches, any devices beginning with the letter "C" will handle most everyday electrical applications but when devices are used in factory environments or subject to impact or hard use, go with the Tri-Axle truck, use devices with the "BRY" prefix.
What are the holes for in the end of some of the 15A and 20A straight blade plugs?
These are optional per ANSI/ NEMA WD6. They can be used for manufacturing carriers. The holes were there to help with plug retention. Some manufactures put small bumps on the contacts in their connectors and receptacles. The bumps engage into the holes. UL standards no longer allow this as a retention aid.
I want a 20A 120V a straight blade receptacle with two vertical blades and a ground.
A 15A 120V receptacle is a NEMA 5-15 configuration, it only accepts a plug with two vertical blades and a ground (if present). A 20A 120V receptacle is a NEMA 5-20 configuration, one vertical slot (hot) and a T slot (neutral). You can plug a NEMA 5-15 plug (two vertical blades and a ground) into a NEMA 5-15 and 5-20 receptacle and connector. You can only plug a NEMA 5-20 plug (one vertical blade and one horizontal blade) into a NEMA 5-20 receptacle and connector.
Do you manufacture any straight blade plugs that provide for crimp connections to the blades?
We don't manufacture plugs with crimp terminations. The only plug we make with terminals different than the screw/ clamp type is the 5966VBLK which utilizes an "insulation displacement" termination.
Can I get a Hospital Grade device without a green dot? I don't like the way the green dot looks.
All UL Listed Hospital Grade devices have the green dot. The green dot indicates to the user that the product is Hospital Grade. If it isn't a Hospital application, you might want to consider using our Extra Heavy Duty Industrial Series.
Which receptacles have the highest pressure contacts?
UL dictates how "tight" we can make the contacts. Generally they have to hold a plug attached to a 3 lb. weight but they have to drop a 15 lb. weight. Our top-of-the-line Extra Heavy Duty Industrial Series (BRY5362) and Hospital Grade (BRY8300) devices are considered by most as the best in the industry. We use solid brass contacts and a patented design to make these devices last the longest and survive the most abusive and critical applications. All receptacles leave the factory at the upper end of the UL tolerance, these devices will stay that way the longest. In the relatively mechanical stress free receptacle life of high-end audio applications the top-end receptacles would outlive the equipment plugged into them.
Do you sell a NEMA TT-30 configuration?
At this time we do not manufacture a NEMA TT-30 configuration.
I have a 20A 125V duplex receptacle, do I install it ground up or down?
We recommend ground up. UL or NEMA does not indicate ground up or down, the positioning is a matter of choice. The rationale is that a metallic object falling on a partially inserted plug will be more likely to contact the ground blade of a three wire plug rather than the hot blade. If mounted horizontally, oriented the ground to the left to have the neutral blade on top rather than the hot blade.
Do you have a 20A 125V receptacle without the "T" slot and only two vertical slots?
NEMA 5-20R receptacles have one vertical slot (hot), a "T" slot (neutral) and a ground slot. A receptacle with a 20A configuration will accept a 20A plug (NEMA 5-20P has one vertical blade and one horizontal blade and a ground) and a 15A plug (NEMA 5-15P has two vertical blades and a ground). A NEMA 5-15R receptacle has two vertical slots (hot & neutral), and a ground slot. A NEMA 5-15R receptacle will only accept a NEMA 5-15P. (NOTE: Both NEMA 5-15R and 5-20R receptacles will accept NEMA 1-15P non-grounding plugs)
Do you sell a NEMA 7-20 configuration? I see the configuration on your chart but no catalog numbers? Is this a miss-print?
At this time we do not manufacture a NEMA 7-20 configuration. It is not a miss-print. We can offer a NEMA 7-15 configuration.
Can you use a double-pole switch to control two independent 120VAC load circuits, each load circuit supplied a different phase ("hot" / ungrounded) conductor from a 240VAC supply (ie, 120/240VAC Edison circuit supply), with each 120VAC "hot" protected by two separate single pole breakers?
No. That would be either the job for two independent single-pole switches, each on its own respective single-pole breaker, or one switch that is fed with a 2-pole common trip breaker. Both scenarios would ensure the switch is de-energized if the breaker(s) is toggled off or trips off.
Do you have a Hospital Grade Switch?
No one sells Hospital Grade Switches. UL does not have category for Hospital Grade Switches. Typically our Industrial Series Switches are used in Hospitals.
Do you sell the two push button switches and plates anymore?
What is the endurance test that a switch has to pass in order to be Fed Spec?
Single pole, double pole, 3-way and 4-way switches have to pass a 50,000 cycles minimum, tungsten filament lamp load at rated current in order to be Fed Spec listed.
I can not find a DC rated switch in your catalog. Do you sell one?
We no longer sell a AC-DC rated toggle switch. Customers have told us they would typically use a single pole switch to control a DC rated relay.
How many keys come with your locking switches?
Two keys are supplied with our barrel key locking switches and one key is supplied with our slide guide key locking switches.
How do I wire up your 3025 series switches for my generator application?
The 3025 series switches are not listed as transfer switches, we can not recommend it for your application. You should contact Hubbell Industrial Controls for a listed transfer switch. www.hubbell-icd.com
What wallplate do I use with your 4901RKL?
The SS12RKL single gang stainless steel wallplates can be used with all our RKL switches. (NOTE: At this time we do not have nylon plates for our barrel key switches)
We tested our support grip with a magnet, and it stuck to several parts of the material. Does this typically happen with 302/304 stainless steel, or did we get the wrong product?

Why is there a safety factor on Wire Management Products?
Our published breaking strengths are determined using brand new grips under laboratory conditions, uniform loading, and metal banding on metal rods. The actual breaking strengths may vary by as much as 20 percent from the published values. We recommend a safety factor of 10 for support grips as there are many unknown variables including age, corrosion, loading conditions, type of cable being supported, lack of supervision or inspection after the install, etc. We normally recommend a lower safety factor of 5 for pulling grips because they are not permanently installed, they are used more like a tool under constant supervision. We recommend that all the products to be inspected for damage or wear before and after each use.

Using a standard 500 volt megger. What should the resistance be from the isolated ground screw to the grounded portion of the device, what is the minimum reading that these devices are manufactured to achieve.
Using 500 Volts the resistance should not be less than 100 megohms.
When wiring a device, why does the installation instructions indicate do not tin conductors?
Wire tinning, for the purpose of containing loose wire strands, is not a recommended practice for use with clamp/ screw terminations in wiring devices. The thermal properties of solder tend to allow for the redistribution of wire strands, particularly due the heating and cooling cycles common to wiring devices. This occurrence is commonly referred to as "cold-flow." In long-term usage, cold-flow could result in a runaway thermal condition progressing to excessive heat, arcing and/or fire.
What are Arc Fault Circuit Interrupters (AFCIs)?
AFCI's involve a technology that detects arcing-faults in electrical circuits that could cause fires. By recognizing characteristics unique to arcing and functioning to de-energize the circuit when an arc-fault is detected, AFCI's further reduce the risk of fire beyond the scope of conventional fuses and circuit breakers
