I'm about ready to pull my hair on this one. I built a service 4 years back for landscape equipment only. It has a 125a panel with two 15a circuits. Each circuit feeds one gfi mounted directly below the panel. One circuit is for lighting and one for sprinklers, and one gfi has been replaced at some point so light is cooper and sprinkler is P&S.
The sprinkler gfi trips for no reason I can find. When owner first found it, simply plugged sprinkler into light gfi. When I was called I went and looked at it and I could see nothing wrong. Cycled the sprinkler and held fine. Called the owner and he said it only did it when lights turned on. Well, that's unlikely since they are on separate circuits, but ok ill cycle them. Worked fine, so I left them separate.
Texts me me the next day, tripped, and owner combined again. This time I swap out the gfi, and cycle everything, works fine.
Texts me the next day, tripped. That's really odd. Maybe the tolerances between cooper and P&S aren't the same? So, I go and get a cooper, cycle everything and works fine. I even change pigtail which has a 90 degree end on it, in case the molded plug has a intermittent short.
Get another text ... This time I completely rewire whole thing from breaker to gfi. This was last Friday. He checked over the weekend and worked.
Got another text today ...
I'm at a loss. I thought maybe a bad control, but he said it is brand new. It only runs two stations, and I've ran then for 5 mins with no problem. It would work fine with both light and sprinkler on same circuit, but that's not the issue.
Any thoughts?
