Glad to hear you may have fixed the problem.
Just a thought, I am no expert... but your voltage at 215V is on the extreme
edge or outside of some power companies voltage spec's and I doubt that is
good for your appliances, especially motors, in the long term. Nominal
voltage is 240V, not 220. The spec for voltage at some power companies is:
normal range 240+/-5% or 228-252, extreme conditions 240 +/-8% or 220-260.
Outside of the extreme range, the power company is obliged to fix it on an
emergency basis. Don't know what the specs are for your supplier but may be
When mine was high but within extreme limits, I was going to ask the power
company if they couldn't fix it by changing the power tap-off on the
transformer feeding the house. Fortunately they fixed it for everyone in the
neighborhood with new power lines.
Just my 2 cents.
Yes, so far, over a week has passed with two below zero nights and no
further problems. It appears to have been a poor connection between the
master breaker and the pump controller.
I may just contact CL&P about this low voltage. It's okay in winter, but
annoying that I can't use the overhead fluorescents in summer because of
insufficient voltage. My TrippLite LC2400 line conditioner is always showing
"extremely low" line voltage and is stepping it up to 127vac at it's output.
