Just for grins and giggles the other day I stuck an amp meter on the wires coming out of the 2 pole breaker for the Voltec while it was running. One leg read 15.8 amps and the other 14.3 amps. Seems like I was seeing the number 3.3 kw tossed about as the max power usage during charging but this would appear to be higher than that.
I guess if 16 amps is the highest usage then 3.840 kw would be the max theoretical usage, although if my voltage was a little lower I might have slightly higher amp readings. Typically my voltage is in the 115-118 range.
Is the 3.3kw an average number? I know many chargers start off with high power and the taper down as the charge completes.
Maybe some of you guys with 240 chargers that have built in watt meters could chime in.
