I've replaced the outdoor electrical service for my house.

My next electrical task -may be- to replace the old waxy-cloth covered wiring inside the house.

All the wiring inside the house is (i'm guessing) a mid-20th century upgrade. All conduit, all the time. Inside the conduit are said waxy-cloth wires.

So . . . . What say you? Do I need to replace this wiring if it's not 'broken?"

If so, can I just remove it and shove some romex through the conduit? (if it will fit)

I like the conduit, actually. The walls are plaster and lathe, so just shoving new wiring through the conduit is a quick and easy idea, if that's acceptable.

thanks
