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 wiringand 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 areawith wallboard, virtually eliminating floating installations• Matching thermoplastic wallplate included
