OT - Strange GFCI Behavior - Deadly!

DerbyDad03 · 2023-06-20T02:02:58+00:00

Just to save everyone some typing, I know a GFCI works and I've installed dozens of them over time, both as standalone devices and as protectionfor downstream receptacles. Line vs. load, Pre-2006 devices, Post-2006 devices, etc.Anybody ever heard of a case where the GFCI acts like this:Press the test button and the GFCI "trips" - the button pops out and thedownstream receptacles go dead. However, the GFCI itself is still live.A tester shows that the GFCI is wired correctly, at least as far as hot,neutral and ground are concerned. I can only assume that something is wrong internal to the GFCI but if that's the case, that's a really dangerousfailure mode. The homeowner doesn't know when the device was installed and isn't a family member or close enough friend for me to start messing with wiringin a 1940's era house. I shut off the breaker and told her to call an electrician. I've seen GFCI's fail, but not like that.

Probably not the rule but If I am going to leave a receptacle filled it will be the bottom one so that the top will be visible and unobstructed.
