Eaton TRGF20W White Self Test Tamper Resistant GFCI Receptacle 20 Amp - This GFCI Receptacle has a slim design for easy installation, leaving more room for wires in the box. Its child-safety black tamper resistant shutters help prevent improper insertion of foreign objects such as keys, hairpins, etc. The nickel-plated stainless steel strap and screws allow for added corrosion resistance. It incorporates lock-out functionality to protect against mis‑wired line‑load connections and GFCI circuitry damage. An automatic grounding system eliminates the need for bonding a jumper in grounded metal enclosures and provides a redundant measure of ground continuity where a jumper is used.
