I am having trouble with one 110 VAC power to the house. The line
keeps vering between 115 VAC to under 90 VAC. The house is wired from
the power Co. with two hots (110 VAC) and a netural. I am having
trouble with one phase (110 VAC) and the other phase (110 VAC) does
not fluxuate. What could it be? I have had an electrican and he is
stumped, and the power Co. is no help.

More information: The is a voltage drop early in the morning when the
city is comming alive (5:00 to 9:00AM). I will check all connections
on my side of the breaker box and look for an open netural. When I
bought the house the builder had not connected several grounds on some
outlets. A loose connection would give the trouble, except I only see
the problem in the evining (7:00 to 10:00 PM) and in the morning from
(5:00 to 9:00 AM). During the day the voltage a solid 116 VAC. The
power company will get another call and I hope to get a rep. who
understands my problem. I am testing the circut with a DVOM and the
voltage get's down long enough for the meter to respont.
