hello everyone,
My GFCI continues to trip. I replaced it, same problem.I rewired with 12-2 for 20A breaker and GFCI. Itcan take over a day to rese without anything pluged in. Only one other receptacle is on this line. What I don't understand is that that load is 14-2 with 15A receptacle.(I did not wire that) I tried to isolate bot the pond pump plugged outside and the alarm system. Alarm only= trip, pond only= no trip. I also plugged the alarm by extension to a basement recpticle= no trip at the breaker. I was thinking that the pond pump might have a short but it has not tripped in 25 hours, the wire leading to the pump has not been rewired nor has the breaker been replaced. I was thinking of replacing the GFCI with a 20A receptacle and or disconnecting the load after the GFCI.all worked fine before the storm. I thought also that the Alarm may have shorted but it has not tripped the panel breaker as it had the GFCI.

Any Ideas?

Thanks----Don

The problem may be a ground fault in the alarm system that the GFI device is sensing.

Water may have entered the cable, or alarm.

A standard breaker is not as sensitive as a GFI device, however you cannot leave it on a standard breaker.

A GFI device will also trip due to length of wiring and not have any actual ground fault.

Has this system worked fine for some time, or is this a new system?

Everything has worked for some time. It does not matter if the pond is plugged and/or alarm. The only thing left to replace is the breaker or the load wire all else is new. The breaker is now tripping with pump only. I'm thinking the problem might be the wire that is the load. How wolf I test the alarm for a fault?
