White 20 AMP industrial grade duplex receptacles are used to provide protection to critical equipment. Garvin Industries’ industrial grade duplex receptacles have a durable impact resistant body. They have tapered lead-in slots on the back wiring holes that make gathering standard wires fast and more secure. Their automatic grounding system eliminates the need for bonding jumpers in grounding metal enclosures and provides a redundant measure of ground continuity where jumpers are used.
