Locking Receptacle, L21-20R, 20 A, 120/208V AC, Three Phase, 4 Pole, Flush Mount, Screw Terminals
The Locking Receptacle from Hubbell Wiring is designed for three-phase applications, offering a reliable and secure connection in high-impact environments. Its insulation barrier construction isolates the ground contact from the mounting strap, ensuring a clean and noise-free ground. The receptacle features wire restraint recesses for secure terminal connections and a high-impact nylon face for added durability. Suitable for use in commercial and industrial settings, this receptacle provides a lower resistance ground path and greater resistance to corrosion, making it an ideal solution for applications where reliability and safety are paramount.
Top product features:
- 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
- All-brass mounting and grounding system provides a lower resistance ground path and greater resistance to corrosion than steel mounting systems
Top product applications:
- Industrial Control Panels
- Commercial Construction Sites
- High-Density Data Centers
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.
