Here is a good one for you guys to think about and figure out. It was a actual problem that took me a while to find.
House was built in the 1950's has no k&t but some cloth romex and some of the more modern romex.
Has a recently upgraded 200 amp main breaker panel and service done by others.
Had a recent basement rewire done by others as well.
When standing by any operating light, and turning something...anything else on....the light will either flicker or dim to a lower intensity and then after the load seems to stabilize, the light will return to full brightness.
Homeowner states that the problem was not present until after all the previously mentioned work was accomplished. The prior contractor tried to determine the problem but it seemed that when they could not find out what was causing this, they kind of disappeared off this job.
So here comes your favorite resident sparky....to the rescue I hope
Voltage reads normal at the meter socket and main panel. Everything is grounded as it should be per NEC. Nothing real major going on electrically in the house. The biggest circuit is the range and then the AC. Everything else is gas.
I found the problem....might be a good one for you HI's though so have fun
