I have a 20A circuit which feeds a string of 3 receptacle outlets in the garage, and 3 in the house. The junction of the garage-string and the house-string fortuitously is in one of the garage outlets, so I replaced that receptacle with a Seymour/Legrand GFCI receptacle, hooking the line from the service panel and the house-string to the line side of the GFCI, and the garage-string to the load side. When I restored power, the GFCI tripped.
After some troubleshooting, I find that with the load side of the GFCI (the garage string) disconnected, and nothing plugged into the house-string receptacles, the GFCI trips when power is applied. With the breaker off, I measure infinite resistance between the hot side and ground, so I assume there's a problem between the service panel and the GFCI, but I'm at a loss to see what it might be.
I have tried 2 new GFCIs with the same result.
Any ideas?
