Thnaks for any advice.



Do you have an electric dryer? Do the same "experiment" with the
dryer.

Are all the "dead" circuits on the same "leg"....all odd or all even
numbered breakers?
From the symptoms you describe, sounds like you've lost the neutral or
its damaged / high resistance.

Most likely the problem is on the power company's side. Call the
power company out & have them do a proper neutral test, not just with
a voltmeter but where they pull the meter and load test each power leg
and neutral.

I had a similar but must less severe situation that existed for years
(like 8 years) where the living room lights would brighten when the
electric dyer was run. I had Edison out a couple times & an
electrician as well......all visits resulted in "no problem found,
everything is ok" or "the problem must be on your side of the
meter" comments.

Finally after storm & a power outage, the neutral deteriorated enough
to make the problem more acute. My neighbor hounded Edison enough to
where they finally found the issue, admitted it was on their side of
the meter & fixed it.
