I have a house from 1960s. I need to extend a cloth covered wire (contains hot, neutral and ground wire). Can it be safely done with a romex 12/2? This is for a light bulb.
So I just wire the respective wires together (hot-hot, neutral-neutral, ground-ground) with wirenut and that's it? This will be in my attic so I'm not sure if I should leave connecting wires exposed like this and in contact with insulation. Electric tape the wires/wire items too?
