[quote=Anonymous][quote=Anonymous]This is a major fire hazard. Knob and tube wiring is ungrounded. There’s a lot of it where I live and it costs $30-75K to replace depending on size of the house.[/quote]

Most electricians feel properly installed knob and tube is quite safe. If you don't believe me, go to a site that specializes in electrician discussion like mikeholt.com and search the archives.

If the fuse box has been upgraded to breakers, the lack of grounding can be addressed by putting in a ground fault circuit breaker.

There are a few problems you typically see with knob and tube. One is that the circuits lack sufficient capacity, both in amperage and in number of outlets. This leads to people running extension cord, which creates all sorts of hazards.  Another is that it often gets added onto in unsafe way; the knob and tube itself is not unsafe but the add-ons are.

Some insurance companies won't insure houses with knob and tube, nor with fuse boxes. That can be a major problem. [/quote]
