Single Charger w/ HWPC on 208v - Can I use a higher amperage?

    Question:

    I have a single charger, and am thinking of purchasing an HWPC for a cleaner install in my condo. My condo runs on commercial power, 208v. Typically, people run 220v @ 40amps and that is ideal/max possible with a single charger. But, with commercial power, can a single charger take in more amps? I see that the HWPC can accomodate a lot of different breaker sizes (60A, 70A...).

    Man you could really dress up a 14-50 for 1200 bucks.

    I could. But my other reasoning is that I can sell the hwpc for a smaller loss than any custom things I do to the 14-50.

    I doubt it. I suspect the chargers are actually rated by current, not power.

    I don't think we have a definitive answer on it but all engineering reasoning would point to the main limitation being current (because wiring and circuit board traces are based on current). To validate, we need to see if a 208V-connected 60A+ charger allows higher currents to be set when connected to a single-charger MS.

    Will the Condo allow you to just yank the HPWC out when you move?

    Yea, they want any outlets and equipment removed that isn't being used.

    K then probably a good point. I'm guessing there'd be a large market for used HPWC's at less cost than new.
