This line of GFCI receptacles ensure electrical shock protection with periodical automatic testing. If no GFCI protection is present, the receptacle will render itself inoperable and a red indicator light will glow notifying the user there is no power and the device must be replaced.DESIGN FEATURES: - Performs periodic self-tests to ensure integrity of GFCI protection- Visual trip indicator light gives quick notification of a tripped or “end of life” condition- Meets and exceeds 10 kA short circuit testing and Underwriters Laboratories (UL) UL943 safety standards- Automatic grounding system eliminates need for bonding jumper in grounded metal enclosure, provides redundant measure of ground continuity where jumper is used- Ground termination with back wire clamp provides secure wiring and reduces installation time- Line side terminals are backed out and staked for fast installation- Horizontal test/reset button alignment provides larger unobstructed area- Test and reset buttons are color matched to provide superior aesthetics- Tapered back wire openings handle multiple wire sizes and types for applications up to #10 AWG solid or stranded wire- When downstream receptacles are wired from load side, a 20A feed-through rating offers full protection- Line-load miswiring protection: GFCIs will not provide power downstream when wired incorrectly- Tri-combo head terminal and mounting screws- UL Listed, fully compliant with all latest UL943 Class A GFCI requirements- Longer, wider “bridged” strap provides 40% more contact area with wallboard, virtually eliminating floating installations- Matching thermoplastic wallplate included
