I have a question for you? When, or what time frame, was the old knob and tube wiring installed? Was it in the 20-30's 30-40's?
Thanks, dave

1882 house had it.
1921 house has cloth 2 wire
1959 had modern style romex but was missing the ground.

Some examples I have ran into.

I'm only in my 20's and have worked on over 10 knob and tube houses. All from 1830 to 1920. The early ones definitely had been remodeled around 1900.

Reason why I asked the question, worked in a house today doing some drywall repairs, and the HO said the house was built in the '50's 1950!
has the old knob and tube in the attic and the basement, romex in the walls we are repairing. The house has smooth block walls in the basement, not like my own house that has the "wavy outside" block that is older.

K&T in a 1950 house does sound a bit odd, at least for PA. That certainly wasn't the standard at the time, though I have no idea when it became non-code.

I grew up in an old farmhouse built in the 1850's, and it had the cloth twin-conductor. No idea when the wiring was put in.

Here's a question. When was the first year they used building codes? I thought it wasn't till the 60's
My last house we remolded the bathroom it was built in 1959 and had a plumbing inspection sticker stapled to the stud. That is the oldest inspection sticker I have ever scene.

I think the first UBC was in the 60s but there's evidence of building code going back more than a thousand years. I remember seeing it, it was something like; if a man builds a house and it fails and the family living in it dies, then that man and his family shall be slain.
