No. You need a stout (<.2 ohm) 240 or 250 VAC source. You can get 20% more power out of a 250 VAC source at 40 amps than out of a 208 source at 40 amps with the same source resistance.
Normally, 14-50 outlets are wired with larger wire and have less resistance so the voltage stays higher under load. Your PFC-50 made full power off a 250 VAC circuit that was about .4 ohm back to the utility (20 volts of sag at 50 amps). If you want to measure the sag, check the voltage to the charger at no load and again near full load (circuit breaker rating). Divide the voltage difference by the number of amps being drawn. If you are a great distance from the breaker panel or have a small utility transformer, there can be a substantial voltage drop during operation.
