we need to get a battery charger for an electric transport vehicle working in the USA.
We can't simply use another local charger because we have complex features and functions in the charger.

We have a power consumption of 3400 Watts. The chargers accept both 50 and 60 Hz.
There is a 230V 14 Amp single phase version and a 400V 3-phase + N (5 amp per phase) version so we will need a transformer anyway.

Is there a common outlet (as far as I know, three-phase is not available everywhere) where we have the highest chance of availability at the customers site?
Does it depend on the kind of industry?
What about non-industrial buildings, which outlet is the next common behind nema 5-15?

Thank you all.
