Testing a GFCI is a good way to verify that it is providing protection. While all GFCIs should be tested monthly, users often forget to conduct this test on a regular basis. Now there is a technology available that can supplement the manual testing and regularly conduct an automatic test of the circuit. In June of 2015 there was a revision to the UL (Underwriters Laboratory) standard 943 for Ground-Fault Circuit-Interrupters that improves safety for the end-user by requiring GFCI manufacturers to integrate an auto-monitoring (self-test) feature that performs a periodic test to confirm that the GFCI can respond to a ground-fault and, if not, it must visually and/or audibly indicate to the user that it needs to be replaced.
- GFCI will continually test itself and alert the user if protection has been compromised
- Patented reset lockout feature prevents the GFCI from being reset if it cannot respond to a ground fault
- Conformal coated PC board to protect critical components from moisture, stainless steel straps and mounting screws and UV stabilized engineering thermoplastic
- Reduced depth makes it easier to install in electrical boxes
