I am going to buy a stud/wire/voltage finding tool today, but I was wondering if anyone has a good idea to help with my problem. During the summer I have been fixing up a small shack in my yard, turning it into a workshed. There I've installed fluorescent light fixtures and electrical outlets for all my various tools. I pulled a main power line from the shed into my house intending to connect it to the circuit labelled "outhouse" in my circuit breaker cabinet. However, the problem is that I can't find the lines coming from this particular circuit. There are 14 various circuits in my house, all with their own circuit breakers - and the one labelled "outhouse" is number 12. So, the previous owners upgraded the electrics and at the same time had a circuit for the outhouse installed, but never got further than that. I've been scratching my head, using my multimeter and flipping circuits one after the other trying to find the appropriate lines, but so far no luck. So my question is; are there any electricians on here, or anyone with experience in these matters, who can advice me on how to trace the lines going to the appropriate circuit?
