….go barefoot. An old proverb that speaks to those with particular skills and aptitude often taking care of their own stuff last. And usually the case with me!
I had a couple of basement outlets / lights go intermittent, I tracked it down to a particular outlet, and so far as a bad neutral (because the voltage tester was chirping on a “dead” outlet.
This noontime, I pulled a shelf away from the wall, pulled the outlet, and heard the familiar (and unsettling) crackle-crackle of arcing as a nearby light on the circuit blinked.
The sparky-monkey who wired the basement (no doubt the former owner) used those stupid / dangerous outlet holes to make connections (called “back-stabbing”) One neutral connection was high resistance, getting warm, and thankfully broke connection before anything caught fire.
I cut out the outlet, replaced with properly screwed down and wrapped around the terminal connections, and all better.
Best of all, since the circuit in question also powered my desktop computer, I got to listen to my UPS chirp while I made the swap (NASCAR-like) and returned the circuit to service with 12 minutes to spare (my UPS is oversized for the load, so lots of battery time).
