Electrical troubleshooting: what's my next step (see details)
An electrical circuit went dead in my house the other day. I went to reset the breaker, and found the breaker switch for that circuit (we’ll call it circuit “a”)had not been tripped. Suspecting a faulty breaker, I changed the breaker with one I knew was working correctly from what we’ll call circuit “b”) Circuit “a” is still dead with the breaker from “b”, and the circuit “b” is still supplying power to with the breaker from “a”. So the fault is not with the breaker.
The next thing I suspect is the wiring in circuit “a”. I did a continuity test at the panel, and there is no continuity at all. Where do I go from here.
BTW, I have followed all safety precautions.
