Live in a 30-year-old house; among other things we've done, I've been slowly replacing all the electrical outlets and light switches - both for aesthetics and because they're so old that they're loose.
Today I changed out all in the master bedroom and upstairs hallway. When I flipped the circuit breaker back on, it tripped. I went upstairs, checked all the wiring, saw nothing, flipped it again. It reset - but when I went upstairs again, still no power. I went back and (after flipping the circuit breaker off of course) disconnected every outlet and switch I messed with today, leaving the wires all dangling but absolutely not touching each other nor anything else. Flipped the circuit breaker again - it still stayed on without tripping, but still no power at any outlet or switch. Ideas? Think the circuit breaker is bad?
