Flickering Lights Whole House
BTW, what is your definition of flicker? Do the lights go totally out or do they just go dim?
After many wrong guesses by electric company personnel, the lineman supervisor found the problem to be the clamp that held the neutral wire to the meter box. The clamp was loose, and when it jiggled (and why it would jiggle, I don't know) every thing flickered. Replacement of the clamp resolved the problem.
Don't let them convince you to do anything until they are positive that they have isolated the problem.
I guess if the wires get loose over time, they can arc and cause the flickering.
He said it has worked so far
In the picture enclosed, it is the large flat blade/standard lug terminal on the bar that spans the primary/right buss under the Hots to the left neutral buss.
Thanks to everyone who's posted what their solutions were. I'll update if/when we figure out what our cause is. I'm hoping it's in the main panel and easy to fix/replace.
