Re: Pull New Wiring
Around here I see bx behind plaster lath more often then nm, obviously both practices were in use at the time, just dont see much of it, I suspect at the time there may have been some local bias toward the bx wire and away from the nm. Personally I think the bx can be worse then the knob and tube.
