20 A GFCI Receptacle for Commercial Circuits

This 20-amp, 125-volt GFCI receptacle is built for commercial and industrial wiring where ground-fault protection is required. It accepts 5-20R plugs and installs in standard device boxes. The audible snap confirms a solid connection during installation.

Patented AUTOGUARD Self-Test

Patented AUTOGUARD self-test technology runs automatic diagnostics to verify protection is active. Triple-wipe construction maintains reliable contact pressure over repeated insertions. The device blocks power to the face and downstream receptacles if line and load conductors are reversed.

Fits Standard Boxes and Frees Downstream Protection

The receptacle fits standard electrical boxes and provides GFCI coverage for downstream devices on the same circuit. Miswiring protection eliminates the risk of energised faces when connections are swapped. No additional test equipment is needed for routine verification.
