The circuit in our bathroom is dead. Circuit breaker's not tripped. All started when a bulb was broken off in the socket. Even though the rest of circuit was unlit, there was juice at the socket with the broken bulb. (I don't have a circuit tester, I just got a jolt!) I've removed the entire fixture with the faulty socket, wire nuts to the rest of circuit are intact, circuit breaker reset, but still no power to the circuit. Any ideas?

I am installing a new dedicated circuit for our a/c roof unit. The unit draws 28.xx amps, and the service plate requires a MAXIMUM overage protection of 40 amps. I happen to already have 10g wire to run in conduit, but I believe that 10g can only be used with a 30 amp breaker. Can I run the a/c with just a 30 amp breaker, or should I purchase the 8g wire, the larger conduit and run the 40a breaker? The run is under 50 ft. Also, for the mandatory disconnect, I used a 60A box within view of the unit on the roof (the kind with the pull-out 'key') because the next lower available at Menards was a 30 amp, the cost was the same, and this question hadn't been resolved; so i made the larger amp purchase because the ultimate overage protection is at the main panel, right? Finally, the installer hooked up the brown-sleeved multi-wire thermostat line with what the manual indicates are the wrong colors (for all models covered by the manual). Should I connect the correct colors as indicated then run them to the block inside the furnace that then runs to the actual thermostat? Thanks for any input.
