Commercial Grade Construction and features ensure better performance and reliability. High Abuse Nylon, Smooth Surface creates clean upscale look. Manufacturered by Cooper/Eaton for Hubbell. GFCI provides protection from dangerous electrical shocks caused by ground faults. Our GFCI devices automatically self-test periodically to ensure GFCI protection and continuous safety. In addition to being tested to the highest standards to help ensure safety, GFCIs will deny power and prevent re-setting if the device is no longer able to provide safe, protected power. The built-in indicator lights provide quick notification of a tripped or “end of life” condition. Performs self test to ensure integrity of GFCI protection, meaning an automatic test shall be initiated within 5 seconds of power availability to the line or load terminals, the automatic test shall be repeated at least every 3 hours. The device will trip and will not reset if GFCI protection is not available. The status indicator light will glow red notifying the user there is no power and the device must be replaced. Easy to use horizontal test/reset button alignment for larger unobstructed area. Longer, wider bridged strap provides 40% more contact area with wallboard for better alignment and less floating. Replaces any existing GFCI with similar specs. Measures 2-Inch length by 2.9-Inch width by 4.9-Inch height.
