The radiant® collection is a step up from the standard with simple, classic options in wiring devices, home automation controls and screwless wall plates that complement today's homes.The self-test GFCI conducts an automatic test every three seconds, ensuring it's always ready to protect. If the device fails the test, the indicator light flashes to signal that the GFCI should be replaced. It also has our proven SafeLock™ Protection feature: if critical components are damaged and protection is lost, power to the receptacle is disconnected.radiant® Screwless Wall Plate not included.FEATURES AND BENEFITS:• Part of the all-new radiant® collection.• Protects children: patented shutter system helps prevent improper insertion of foreign objects.• Meets National Electrical Code® Tamper-Resistant requirements.• Conducts an automatic test every three seconds, ensuring it's always ready to protect.
