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. Make sure you can spot ground fault trips quickly and resolve them easily with GFCI Receptacles installed in the living space. For detailed GFCI receptacle information, visit our GFCI Headquarters.
