Today, I had two rooms in my house lose power for no apparent reason. Both rooms are connected through the same circuit breaker, but this didn't trip. I know that there was power in my house earlier in the morning. After checking all the breakers, and reseting them three or four times, power hasn't come back into the two rooms. Using my DMM, I get a reading of 0.3 V at all connections on that circuit. I've checked the power going through the circuit breaker, and it's reading 120V.
Does anyone have any suggestions as to what could have happened to cause a lose of power? There doesn't appear to be a short in the circuit as the breaker hasn't tripped. Could it be that the breaker is bad, and needs to be replaced? All advice and suggestions are welcome, thanks.
