Twist-Lock® Devices, Single Flush Receptacle 20A, 3 Phase Y 120/208V AC, 4 Pole, 5 Wire Grounding, NEMA L21-20R, Isolated ground, nylon, Orange
In February 1968, Hubbell patented the first isolated ground receptacle. Today - when a clean, noise-free ground is more important than ever—Hubbell is still setting the standard. Hubbell uses insulation barrier construction on many models to isolate the ground contacts from the mounting strap. The green grounding screw is connected directly to the grounding contacts. In this way, ground contacts are separated from the mounting strap and also from the conventional grounding system. The isolated ground circuit is completed by running a dedicated insulated ground wire from the system ground buss to the green grounding screw.
- Insulation barrier construction isolates ground contact from mounting strap
- Wire restraint recess for both back and side wiring, greatly reduces the possibility of loosening the terminal connection
- High-impact, abuse-resistant nylon face
- All-brass mounting and grounding system provides a lower resistance ground path and greater resistance to corrosion than steel mounting systems
