GFCI Not Resetting Causes

[Desert Spark]

Lol, you have me second guessing myself now but no, that can't be what it was. I would have to kick myself hard if it was. It's one of those small 6 space square d homeline panels. The neutral bar is on top, and I installed the ground bar on the bottom. There is only one large lug on the neutral bar and that is where I landed the feeder neutral, along with the neutrals from the two branch circuits.

I won't be able to see it again till hopefully this weekend when I can do the trenching but I will see if I can replicate the problem and I will report back.

There was a lot of voltage drop on the feeders when I did turn on the hot water heater, down to 80v, so I know that beside only being the two conductors, they are not even able to supply a 1500w resistive load. There may be other wiring issues in the bunkhouse too. If I can get the same thing to happen, I'll de-term all of the other grounds and neutrals and see what happens to start.

If that can't be what it was, then, you explained your situation incorrectly.

So far I have to agree.

With what has been said so far seems he has new device never been powered before, many are shipped in condition that they need to be reset on first use. If the device isn't seeing voltage it won't reset. This is more of a side effect of line to load reversal sensing function than an intent to not reset without incoming power. Once it is reset you can lose and regain power, as well as reverse line and load and it won't trip because of those actions. But will not reset again if it does trip until line terminals are receiving voltage (not sure how sensitive they are when it comes to what voltage is needed to allow reset)
