Default I have an entire electrical circuit that appears to be short...

I have an entire electrical circuit that appears to be shorted. 110 V on both the ground and hot connections on wall outlets. When this happened, the lights that were on at the time slowly dimmed and went off. If you flip a wall switch for the circuit, the lights flicker & go back off. Even though there is a shorted condition at the outlets, no breaker tripped. However, with the breaker to the circuit turned off, checking the wall outlets with an ohmmeter (the hot and ground connections) indicated a shorted circuit. I disconnected the hot wire to the circuit from the breaker (in the breaker box) and the disconnected the ground wire from the ground connection (in the breaker box) and checked the two wire with an ohmmeter. They did not indicate a short circuit??? HELP

How are you measuring the voltage on your wall receptacles? If you are putting one lead from the volt meter, to the hot wire, and the other lead on the ground wire, and are reading 110 volts, that is a correct reading and not a short. To check for a short in a circuit, you must have all devices (lights,etc.) disconnected, and check for the short at the panel, with the wire disconnected from the breaker, and the neutral wire disconnected. If you check for a short circuit when a lamp is plugged in, you will have a false short reading. When using a ohm meter, a reading would indicate a short.
