Re: Topband: twisted house wiring

 As I remember it from an electrician that married a 2nd time to my Aunt. hi.   
The ground lost its connection and the coiled wrapper became hot like a "hot 
plate" carrying the current.I was about 10 years old then and just wondering 
how a radio worked.

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.

Re: Topband: twisted house wiring

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.

Appears to be induced into the attic 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.

Topband: twisted house wiring

[K1FZ-Bruce]

Live near a housing development with many tenants. The high line on the road is 
about 20  feet diagonally from my attic.  Getting a lot of noise even with my 
house main breaker off.
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.
