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.

• For an added layer of protection, the GFCI regularly conducts an automatic internal test to confirm that it can respond to a ground fault
• Provides continuous ground fault protection - detects and trips on actual ground fault even when self-test is being conducted
• Status indicator light shows power and protection status as well as indication of line/load reversal
• Slim, shallow design - reduced depth makes it easier to install
