I will be the first to tell you I don't know everything. I don't have much experience with K&T and I am looking at doing a service upgrade on a house that has some K&T, not all just a couple of circuits. It looks like the circuits that are K&T are the orignal general use circuits to the house. The K&T wiring is in good shape, bendable, no cracks, it doesn't appear to have been over heated. The home owner doesn't want to open up the walls, so I was going to cut out half of the K&T circuit, there are no outlets on this section, set a 4x4x2 non-metallatic junction box and bring the remaining K&T in on opposite sides of the box, then tie in with romex and run back to the new panel. I ran this by a friend of mine at the local inspection office and he saw no problem with it, as long as the existing K&T was it good shape. I read this board alot and was wondering what was your thoughts or suggestions.
