I installed a vanity in a old house in New London, CT. The BX only had 2 wires for the original light & 2-prong outlet. Fortunately the jacket was grounded although it had never been connected to the old fixture. I needed the ground for the new GFI outlet.

How did the metal wrapper get hot? Was current passing througgh it? The BX I 
had included a ground wire; maybe the earlier BX used the wrapper as the ground.

Appears to be induced into the attic wiring.

Question. Anyone tried some form "twisted pair with green wire"  house wiring 
to reduce noise ?
If Yes, how did it work ?
Wiring laws vary from state to state.   If anyone has something that worked, 
then I can ask local electrical law enforcement about it.

Years ago they had a BX cable   . It was twisted wires inside a metallic 
wrapper.  When I was very young they used to think the metal wrapper got hot 
and started house fires.
