12 stalls, at 250kW each, is 3000kW. Clearly we don't expect all getting the max simultaneously, but I'm curious about the load balancing.
How much do they over-provision? For this 2000kVA transformer, what would be the max that the site should pull? I know this isn't subject to the same codes as my charger at home, but using that as an example, I have a 48A charger and overprovision the circuit by 25% (so 60A).
