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.

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.

Yes, the BRY501xxxxW series of weatherproof cord reels are sold with no ends.

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.

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.

Cam-Type Device Connectors can not be used with motor loads, they do not have UL or CSA horse power ratings.

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.

The Cam-Type plug and connectors are UL listed for Type SC, SCE, SCT, PPC and Type W, PPE cable.

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)].

The cable that can be used is either a 5 mini coax, 75 ohm, shielded cable or SVGA or VGA cable. A couple of the cable companies that manufacture this type of cable are Belden, Madison and Comscope. The distance limitations are 150 ft @ Resolution : 800X 600 or 75 ft @ Resolution :1224X768.

No. You can us a jack at a lower speed, but not at a higher speed. IE; a Cat 5e jack can be used as a USOC jack, but a USOC jack can not be used for Cat 5e jack.

NSJUBK

The UL standard indicates that a 300 pound load is applied with a 3" diameter cylinder 1" long for 1 minute and the cover cannot deflect more that 1/8". A permanent defection after 1 hour of force removal cannot measure more than 1/32". See UL514A & C.

GFP15A meets UL & CSA watertight requirements, adhesive bonded.

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.

The terminal screw torque is typically 14 to 16 in-lbs. But always reference the supplied installation instructions.

It is 150kHz to 230 MHz.

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.

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.

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.

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.

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.

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.

No, Bryant GFCI products should not be used on 50Hz.

Bryant does not have a split circuit ground fault receptacles available at this time .

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

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.

Currently our GFCI receptacles do not have a horsepower rating.

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).

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

Yes, contact Technical Service for information.

Yes, the MSAR (add-a-relay) and MSCU control units are plenum rated.

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.

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.

Yes. Toggle dip switch A4 to on for two seconds, then back to off. The learning process starts all over again.

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.

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.

It is recommended to not exceed 250 feet from the control unit to the farthest sensor, using 18-22 AWG wire.

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.

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.

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.”

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).

No, neither infrared nor ultrasonic technologies can "see" motion through glass walls or windows.

No, just the values change in the sensor's microprocessor.

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.)

Adaptive Technology Wall Switches; 15 minutes (intial setting). Adaptive Technology Low Voltage Ceiling & Wall Sensors; 8 minutes (intial setting).

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.

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.

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%.

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.

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.

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.

The Adaptive Technology sensors will exit the test mode automatically after 1 hour.

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.

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.

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%.

Typically, two or three minutes. Lights are on during this time.

We have a five year limited warranty on the Occupancy Sensor product line.

Yes, they are compatible with all ballasts but, program start ballasts are recommended for lamp longevity.

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.

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.

The Adaptive Technology chip; a small internal microprocessor that combines digital signal processing, control logic and adaptive algorithms (formulas).

Units have been in production since 1997 and reliability has been excellent.

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.

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.

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.

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.

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'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.

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).

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.

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.

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.

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.)

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.

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.

Yes; the replacement switch is 30003DS.

No, our 3R motor controller disconnects be can only be locked in the off positions.

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.

You can use LPS1 (greaseless non-conductive lubricant).

60 degree C rated conductors would apply in this case since the device is not marked otherwise.

Per IEC 60309-1, 32A plugs are tested to 100 Newton's cable pull out.

Yes, Bryant manufactures IEC309-1 Pin and Sleeve devices.

Surge receptacles work across lines, not line and load like GFCI receptacles. Parallel wire the Surge receptacle with pig-tails so it's the first device in the circuit. Wire the standard receptacles downstream not to exceed more than 20 feet away and with-in the same room. Always remember, the best protection will be point-of-use protection.

The QUICK-CONNECT pigtailed terminal on it's own, does not have any effective box fill, according to NEC®2008 314.16(B)(1), since it doesn't originate outside and/or passes through the device box and has leads that are 6 inches long and would not be considered a loop or coil. When installed with the matching receptacle, the assembly (receptacle with the pigtailed terminal) will have a double volume allowance in accordance with Table 314.16(B) for each QUICK-CONNECT receptacle in the device box. Now, assuming that you are feeding the device box with #12 AWG conductors, then your volume allowance for each QUICK-CONNECT receptacle with pigtail would require 4.5 cu. in. (2 times 2.25 cu. in. for #12 AWG).

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.

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.

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.

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.

The CSA standard is C22.2 No. 18.3-04. It is a tri-national standard used in Canada, USA and Mexico.

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.

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.

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.

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.

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.

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.

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.

At this time we do not manufacture a NEMA TT-30 configuration.

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.

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)

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.

The maximum weight rating of our HBL500 and HBL750 series fixture boxes is stamped on the top of the box covers.

Almond devices and wall plates are the best color match.

No. To maintain the UL listing, our metallic raceway can only connect to the competition's raceway with our listed transition fittings.

Yes, we sell touch-up paint pens. Ivory- HBLIWEP, White- HBLWWEP and Gray- HBLGWEP.

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.

No one sells Hospital Grade Switches. UL does not have category for Hospital Grade Switches. Typically our Industrial Series Switches are used in Hospitals.

No. Classic Accents Inc sell the old two button style light switches and plates. Their website is http://www.classicaccents.net

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.

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.

Two keys are supplied with our barrel key locking switches and one key is supplied with our slide guide key locking switches.

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

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)

When using the RU200 with a JLOAD (and partition), the cubic inch capacity available on the power side would be 13.5 cubic inch. According to NEC Table 370-16(b), the maximum allowable amount of conductors would be 6 - #14 or #12. When using the RF500 (or presumably the RJ600) with a JLOAD (and partition) the cubic inch available on the power side would be 7.75, allowing you to use up to 3 - #14 or #12 conductors.

At this time we do not sell residential grade duplex receptacles or switches that will accept both copper and aluminum wire.

Yes, our stainless wallplates have a horizontal brush finish.

The SS8 is manufactured with 302/304 stainless steel (17% chromium, 8% nickel) and the SS8L is manufactured with 430 stainless steel (17% chromium, 0.5% nickel). The 302/304 stainless steel is better for highly corrosive environments and non-magnetic applications.

A wallplate or weatherproof cover with a 1.40" will fill all 15 amp straight blade and locking single receptacles.

We do not have wallplates but we do have weatherproof covers and a adapter. Our WPC1 will accept all our 15A nylon flanged receptacles and inlets. Our WPC2 will accept all our 20A & 30A Twistlock® nylon flanged receptacles and inlets.

302/304 stainless may have magnetic properties. The product is made to be corrosion resistant, which 302/304 stainless steel exhibits. At this time we along with our competitors manufacture support grips utilizing 302/304 stainless.

No. You will need to choose one of our galvanized steel pulling grips. Our grips can be used in salt water, but we recommend that they be washed and dried after every saltwater exposure.

Our grips are only approved for use with wire or cable.

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.

The Deluxe Cord Grips are not electrical equipment operating at a voltage of 50 to 1000V AC in accordance with Article 1 of the Low Voltage Directive (73/23/EEC) in accordance with the Electromagnetic Compatibility Directive (89/336/EEC). Consequently the CE Mark is not required.

No. Conduit riser support grips can only be used in standard electrical rigid metal conduit and schedule 40 rigid PVC conduit. They can not be used in tubing.

Our Deluxe Cord Grips are UL Listed and CSA Certified to the tri-national standard for Conduit Tubing and Cable Fittings [UL514B / CSA C22.2 No.18.3 / NMX-J-017-ANCE].They are approved for use with a cord connected pendant box in accordance with article 314.23(H)(1) of the National Electrical Code®.

To find the approximate equivalent diameter of a multi-cable bundle measure the circumference of the bundle and divide by 3.14.

Our Bryant Wire Management Products cord grips do not have any DNV certification.

For most wire pulls in conduit our underground pulling grips will do the job. If you are have a difficult time picking out a grip, give technical service a call for a recommendation.

Bryant does not sell pipe or wire.

Using 500 Volts the resistance should not be less than 100 megohms.

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.

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

We do not sell explosion proof fittings, you need to contact Hubbell-Killark. www.hubbell-killark.com

If a device has the automatic ground feature; it is referring the ground clip or staple on the bridge of the device. The staple and clip maintain continuity between the bridge and mounting screw. For a receptacle; the ground contact maintained will the grounding path through the bridge to the clip or staple to the metal box. For a switch; the metal wall plate will maintain a ground path through the metal wallplate screws through the bridge to the clip or staple to the metal box.

Listed products are suitable for general-use installations; as such, Conditions of Acceptability (COAs) are inherently not acceptable. Recognized components by contrast are only suitable for OEM use inside some other listed end-products (where UL can evaluate suitability of use in the specific listed end-product by considering COAs for adverse consequences); Recognized Components are not suitable for general-use installations and will be rejected by electrical inspectors if directly installed in the field.

We do not sell pipe fittings, you need to contact Hubbell-RACO. www.hubbell-raco.com
