Yes... sometimes itís funny how we just do things like this for years without actually thinking about it anymore, but when we try to find the where and why... itís as if the original information is long since lost.
Iím currently working on the house from hell, which is a circa 1900 farmhouse that must have been built by Satan himself. The oddball way the rooms are cut up along with willy-nilly cross blocking within the walls is resulting in much demolition. Plaster & lath ceilings covered over with furring strips and drywall are not helping either.
I have finally isolated and disconnected the last K&T circuit in the building, but the owner doesnít want to follow through with replacing all the old cloth two-wire ungrounded NM and two-wire receptacles that were added probably six decade ago, so it will stay as is.
Iím just going to AFCI these rooms on the second floor and be done with it.
Iíve rewired dozens of homes like these over the years, but this one has been the absolute worst.
