Hey all, I'm having a heck of a time trying to figure out what's going wrong with my wiring to my garage. I have a 1905 build house and a detached garage. The panel has been upgraded to 100amps and I have newer wiring running the length of the house to the back. There it runs through the foundation and into conduit where it runs underground using the grey underground rated wiring. It enters the garage and goes to a junction box and from there is distributed thorughout the garage.
Here's what's happening. The circuit breaker tripped (20amp) and I didn't realize it for a little. So I find it, and flip it back on. CLICK it immediately switches off. I flick it again CLICK same thing. Being a stubborn fool I throw it on again...VOILA! It stays on. So I went out and flicked on my garage lights and they flickered in and out dimly. I went ahead and turned them off and went back and thew the breaker off.
I know the issue is not the wiring in the garage after the initial junction box because I just rewired the whole entire thing (it needed it) and am getting the exact same response with the new wiring.
I've tracked the wiring from the panel to the junction box at the conduit outside the house and didn't find any apparent nicks or issues. This leads me to believe my issue is underground between the house and the garage. Now here comes the much awaited question...
How do I test the line to verify this??? Can I use a multimeter to do some tests on it? I'd really like to figure this out and if it means replacing the wire underground, so be it. Just want this resolved!
thanks! Brad
