I watched the electrician install new breakers in the breaker box, string the cable, install a a new breaker right before the SPX Voltec, and then connect it up. As to measuring the actual amount of power, I asked Dianne at Dominion if they can measure that for me. Maybe I should have my electrician do that, huh?Are you absolutely sure that there is nothing else on that breaker with your SPX charger?
What is your typical voltage at your house?
I was surprised to find that the voltage at my house frequently runs at 112v. I have backup system on the computer that displays voltage, and it was showing 112v most of the time...but I wasn't buying it. So one day I brought home a nice fluke meter, and by golly it was right. So if we are starting at 112v and then multiple appliances fire up at the "wrong" time we are easily dipping into the range where one could expect problems.
Need someone with a device that records the power characteristics and records events so it could be determined if the problem was with the supply to the EVSE, the EVSE itself or the vehicle.
