We're thinking of buying a two-story house built in 1940 which has a little knob and tube wiring in the basement, but most of the visible wiring is romex-type cable (there have been a lot of additions and modifications to the house after it was built). It has a 100 amp main breaker panel with breakers, not fuses, and there's only romex-type cable coming from the panel. The current owners (not the original owners) don't know how much knob and tube wiring is in the oldest part of the house, or whether it was ever replaced. The insurance company we want to use, USAA, says it won't insure the house if there is any "active" knob and tube wiring anywhere in it.
Is there an easy way to tell how much active knob and tube wiring is behind the walls, in the ceiling, etc., without cutting holes in the plaster? Unfortunately the attic above the original part of the house is floored, so we can't easily examine the second story ceiling.
I was wondering whether one could take the cover plates off switches and outlets and examine the wiring coming into the boxes and reliably tell whether it was supplied by knob and tube wiring.
Thanks
