Re: Lost power to bedroom
The pinched/rubbed wire can easily heat up without a short due to the decrease in copper conductor area in the pinched/rubbed area of the wire while the same amperage demands is being put on it. Heating wires (like in a toaster) have a small area of conductor which a large current through it - that's what causes electrical heating.
I would suggest splicing out the bad section, mounting the wiring with cable supports to keep it from pinching or chafing again. Do any AC system electrical servicing with the rig disconnected from AC power. After the repair, just keep an eye on it now and then.
