Hey everybody, this is my first time on here. I just bought a house that has knob and tube wiring throughout the attic and second floor. The home inspector said it definitely needs to be switched but the insurance agent says that as long as I install GFCI's it will pass code and be quite safe. I live in an area where most of the houses still have this type of wiring. What do you think?

THanks for your reply K2. It's interesting because my house was recently switched from 60 to 100 amp and at that time new wiring was put in throughout the basement but we cannot seem to find out where they ran it too. I guess it'll just be a search as soon as I get time.

Some old K&T wiring is still in good shape. The places that you should check are in the boxes above light fixtures, even if the fixture looks fairly new. What you're looking for is to see if the insulation has been damaged from heat. With the power off, see if the insulation crumbles in your fingers when you squeeze it. If it does, definitely time for replacement.

As for the GFI outlets, this is a second best stop gap measure. There is no replacement for a real equipment ground wire that is run with the circuit conductors, Also, there are some appliances, of the plug in variety, that are required by the NEC to be grounded.
