Just did a house built in 1957. All looked pretty good, but found this one circuit inside the panel, it looks like AL wiring - on the breaker labelled “RANGE”.
I was told this was original wiring, but original owner is deceased, and grandkids are executors.
The wiring looks good, with no signs of problem.
Was AL wiring used in 1957? And this is obviously not solid AL wiring, but would you report it as “aluminum branch wiring”?
