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.
Try your utility company again. It sounds like their problem.
And they're generally very good about these things in my
experience. Maybe you were just unlucky and got a rep that
was having a bad hair day or somefink.

I don't see how any competent electrician could be stumped. Where is
the voltage being measured? If inside the house somewhere it's 90V,
but it's OK at the meter, then the problem is in your house. If
it's 90 at the meter, it's from there back to the pole, which is
generally the power company's responsibility. Most likely this is a
power company problem.
What exactly did the electrician and power company tell you?
Get the fire dept involved. That's what i did when my voltage was
fluctuating wildly. The power co didn't respond favorably, so i called the
fire dispatch. They said do you have a fire? I said NOT YET, and explained
the situation. The power and light co. was out 15 minutes later with
The fact that your 'other' leg is not wavering is very mysterious. I think
i'd be looking for a bad connection or possibly a bad transformer.
Ask them to put a recorder on your line. It will keep a record of the
This is not usual. Usually it means you have a big power users near by
(industrial?) or they need to upgrade a transformer etc. It is also
possible (depending on how the original numbers were measured) that it is
within your home. A floating neutral will often end up with numbers like
that. In either case you want it taken care of NOW.
i had this trouble once, wierd seeing just part of the house lights go
dim. called power company naturally everything was perfect when they
2 days later the dim side went out and power company replaced the
intermittents can be a hassle to fix, better when something quits
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.
I spent Saturday going through the breaker box, beautiful day to turn
off the heat and found a loose and badly burned buss bolt. I replaced
the bolt, cleaned the connection and replaced one breaker. The breaker
was working but were hot to the touch. We now have a good steady 120
VAC on both legs from the power company. Thanks to everyone for their
If you gave the first electrician any money, you need to stop payment
on the check if possible, or take him to court.
The fault was really *really* basic stuff. A 15 second description at
small claims court in front of the judge will win the case for you
automatically. Just say the problem, what you found, and how any
competant electrician should have had the skills to locate the fault.
