The hallway light would flicker sometimes at night, but if you turned on another light, it would stop.
I used to joke with my wife about loose neutrals, she always knew what it meant lol. With 35 years as an electrician, I’d come home and she’d ask if I fixed it, and I’d say it was a loose neutral. Trust me, I’ve found plenty over my years of service work!
Used a torque wrench to tighten the loose nut
Oh yeah, my guys ended up burning several computers on a 3-phase 4-wire system.
Made sure to tighten it without causing any damage. 30 pounds of torque is quite a bit.
Cut it off and then reinstall
During the replacement, found this in an old fpe panel that has been in place since the early 60s. The setscrew appeared to be tight, but it was actually almost seized due to corrosion. You know, that squeaking sound. Once you hear it, you never forget. It’s a 400 amp residential service with a fuse disco and a pair of 200 amp panels that are finally being replaced.
Half full can versus full can
Not tight.
Time to restrip it, create a solid wire joint, and secure it with some of this wire nut.
Doesn’t seem too concerned about the panel being replaced with a new type of main breaker.
