Quoted from GRUMPY:All 3 machines have 124 volts going into them. Is this AC power within power company specs, yes but at it very highest limits.
No, this is not the upper limit of Voltage for the "power company", at least not around here. 120v +/- 10%. This is straight from my local electrical engineer at penelec. 120v range is therefore 108 to 132v. As a master electrician for 10 years, I can promise you 124v is not the real world high limit. In this part of the power grid, 113v-127 is pretty much the average . Can't say that I've ever taken a meter reading below 110v or above 130v, unless there was a bad neutral on the service.
