Now there is a technology available that can supplement the manual testing and regularly conduct an automatic test of the circuit. Built with a patented reset lockout feature that blocks the Reset button if GFCI protection has been compromised, the GFCIs meet the latest NEC and UL requirements. action prevents reset if GFCI is damaged and cannot respond to a ground fault. After a ground fault condition, unit must be reset. While all GFCIs should be tested monthly, users often forget to conduct this test on a regular basis.
