Thinner than competitors' GFCI receptacles, leaving more room for wires in the box.
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 proven Safe-Lock™ Protection feature. If critical components are damaged and protection is lost, power to the receptacle is disconnected.
