Like everyone else, we are having a heat wave. I live in an area of mainly summer cottages, so everyone is out today with their A/Cs running constantly. I checked voltage at 7pm and it was 106.5v, which is a little alarming. In the winter it is 125v and typical summer is 115v, but I have never seen 106.5v. Is that safe for electrical devices?
I am mainly concerned about the A/C. Trane has absolutely no information on it, but I have read a general article that seemed authoritative that A/C is designed to be 230v and can tolerate 10% up or down; so it is good to 207v. Does that seem right? I checked the A/C nameplate and it says 230v.
By 8pm it had gone up to 110v and by 10pm 112v. I have asked my wife not to do laundry or use the dishwasher except early morning or late evening when the temperature is lower and the voltage higher. I don't know what else I can do; turning off the A/C doesn't affect my voltage.
They are gradually tearing down the small summer cottages, many of which aren't airconditioned, and putting up huge ones; apparently the utility hasn't figured out they have to increase the supply capacity.
