I hope this makes sense.
I have a customer with a conex that has a 100a panel and needs a 100a panel but will pull less when the AC or heat isn't cranking hard.
They want to be able to feed it with either 208 wye three phase or 240v single phase.
I am wondering if wiring it up with a 208 to 240v transfer switch that will take 208 or 240 and feed a single phase panel will be a bad idea with that kind of load imbalance when it is only connected to 2 legs of three phase. This is an industrial type portable unit so a 50a load or whatever normal load it would pull on only two legs should not be a giant imbalance percentage wise, but I don't know how many different places they may plug it in to three phase.
Not sure if I am being paranoid but I'd rather get some educated opinions.
