connecting old BX cable to new romex wiring
I am replacing some wiring, the wires are from the 50's, I believe its BX cabling. My problem is that the old wires are wrapped in cloth inside of flexible metal conduit without a ground.
The new wires of course are line, neutral and ground in a jacket. How can I get the ground from the new cable to connect to the old casing of the cable, do I even connect it?
I was thinking that I would get a metal gang box, connect the ground to the metal box and then connect the old cable to the box to keep the ground going, is that correct? Thanks
