Having a problem with wiring to the Garage. The circuit breaker keeps tripping downstairs in the house. Used to keep blowing fuses in the fuse box in the garage too but I ripped out the old box and installed a circuit breaker in the garage. Installed 30a breakers in the garage and the circuit breaker in the house is a 30a. Now the breaker in the house trips and the breakers in the garage stay on. This is even if everything is off in the garage. I unplugged the garage door opener and now only have the power outlets and a motion light outside the garage. I got to thinking at one time that when it was working fine when it was really cold out and acted up when the snow thawed that it may have been a line damaged somewhere between the 30ft to the house. I got the utilities to come out and mark the lines and I did some digging yesterday. I get down about 8-10 inches and I hit a bunch of old steel cables about every 6 inches and the clay is frozen below that. I rethought my approach and figured screw it! If there is anyway to verify the electrical outlets and lights for wiring are OK and that it has to be the underground wire. If that winds up being the case I'll just contract out to an electrician to come and bury an new cable on a different route. But I got to looking, All the outlets are wired in series. Should I eliminate all but the first to see if the breaker still trips. Also I'm thinking I should Rewire all the outlets Parallel and keep them on a seperate breaker from the lights. Could this also be part of my problem, having them wired in series. I also have a junction box about a foot below the circuit breaker in the garage. I opened and looked at it and verified the correct wiring and the connectors were solid. Weird though. There was actually a red wire, white, black and uninsulated ground. Verified that the red was power with ohm/volt meter and at the box in the house. The red is hooked to the black outgoing. the black incoming was grounded with the uninsulated ground and the white connected to the white outgoing. I have a healthy respect for electricity and had AC/DC Concepts and circuitry in college. But I always want a second opinion on how to proceed because I suck at Bob Villa stuff.
