There are about 5 or 6 receptacles in 2 rooms that all stopped working at once. We were getting a reading of about 92V and it's a 120V circuit. We changed out the receptacles but still the same results. Any ideas for me to fix this? Extension cords through the house are no fun.
When multiple things go out, find out what they have in common.
I'm making a couple of assumptions here, since you changed out one of the sockets, you understand that the breaker must be turned off in order to work on the circuit and that you are actually using a voltmeter to make sure the circuit is dead when the breaker is off before opening up any outlet box. That this is American wiring per NEC. Also that you are not dealing with aluminum wiring.
Depending on the era and the electrician, the daisy chain may be continued by:
My experience with a broken chain causing partial circuit power loss is with an electrician using the push-in connectors.
The failure was due to poor contact and heating that melted the first or second socket because these two sockets have to carry all or almost all the current in the circuit and if the wires don't enter the push-in straight or have burrs that don't allow them to seat properly you get a loose contact that gets worse over time. Heating anneals the brass and the spring contact goes away.
I haven't seen a screw tightened copper wire connection do that yet, they seem to have a larger surface area and are mechanically tightened instead of depending on spring contact.
I have seen burned aluminum screw contacts where there was a mismatch (non-CO/ALR) and bad assembly, that's another scary situation that opens up a whole 'nother can of worms.
NOTE: Grounding was ignored in the above discussion, bare wire goes to green screw ground lug, wire nut with pigtail is handy for this.
