Old Wiring Identification from 1941
The apartments I reside in were built in 1941. The wiring is very old. Copper core with black cloth type insulator. Luckily everything is run in conduit however I found bare exposed wire in some runs. My plan is to pull all new wire in time however at the moment, when replacing switches and outlets, there is no easy way to identify the hot and neutral lines as they look identical. Is there any simple trick to determining which is which with a volt meter? I have one from Fluke very similar to the one in the link below. This will come in handy when adding switches/outlets and also when replacing the lines with updated properly color coded wiring. Also the conduits are used as the ground, no green ground wires in any box.
