Rewiring home from 1947

[AlexNGreen]

Not necessarily garage related but anyways. My home was built in '47 and true to the era has the rubber and clothe insulated wire run through flexible metal conduit. As home improvements have progressed the horrible state of the wiring has been noticed. I have come to the realization that the wiring needs to be replaced.

My question:
I know THHN wire can be ran through the conduit but specifically can stranded THHN wire be ran? Also what sort of termination do you use at outlets and switches?

Thanks for looking-
Alex

You can use stranded wire. Use good quality outlets that have clamping terminals.

Double check as most likely you do not have flexible metal conduit. Most common for that era was AC (armor clad BX) wiring. You can not remove the individual wires from that.

Why not use Nm-B aka Romex? Lot easier than running conduit...

My guess would be that he wants to reuse the conduit to avoid opening walls and fishing wires.

I just upgraded all the wiring in my old house. I didn't open the walls, but I have a bungalow with an unfinished attic and basement that had knob and tube wiring. Probably the easiest setup.

Depending on the style of the house it can range from "not hard" to "near impossible" to fish new Romex through the walls instead of opening them. I have never seen flexible conduit in a home, so I would agree that is is most likely BX, but I think the electricians on here probably know best.

depending on the location and the era there are many homes that have either hard pipe or flex in the walls. my brothers house was built in 1965 in san bernadino and it's 100% flex

You can use stranded wire. Use good quality outlets that have screw clamping terminals.

These do cost a bit more but it is the only kind I would use with stranded wire !!

This is my suspicion as well. Make sure what's installed first, before doing anything.
