Day 4,314: Arc Fault

A well-used circuit in our house has an arc fault. We tried figuring out what was triggering it today to no avail…only to realize that there were more outlets on that circuit! One of which is a on and off flickering bedside lamp! Might be it. Won’t know until we test it tomorrow. I’m hopeful. My first thought, in fact, was that it was this other old lamp of ours. It was the first thing I tested. Plugged it in and the circuit was fine, lol. It’s tricky. Didn’t seem to be any one device being plug...
