Need single line diagrams for 2 new electrical services to feed EV chargers. Must follow NEC, include panel schedule, conduit and conductor information and sizes.
For one of the services, there will be 52 dual Level 2 EV chargers(26 pedestals) at 120/208V service voltage. 2 pedestals are 20 ft away, 4 pedestals are 100 ft away, 4 pedestals are 200 ft away, 5 pedestals are 280 ft away, 4 pedestals are 380 ft away, 4 pedestals are 450 ft away, and 3 pedestals are 480 ft away.
Each EV charger is 7.2kw, 32A output, 208v input.
I'd like to have someone who is familiar with the US's National Electric Code (NEC)
There's two drawings I need. The information above is for the first drawing. The second drawing will be a 277/480v service with (3) 66kw chargrrs, 80A each, with a spare position to accommodate a 150kw charger in the future. Those are positioned 400 ft away from the panel
