(I finally went backwards thru this thread)
. But for some reason everyone gets them installed, when they could have installed 10x Tesla wall connectors or 100x 240v outlets instead, not including utility upgrades. They must have a really good cold-call sales department or something?
Installing Tesla wall connectors is useless for all non-Tesla EVs/PHEVs.
And, as I said in another reply, installing 240 volt outlets is almost as useless, adds more confusion and creates numerous other problems (e.g. drivers needing to buy a 208/240 volt portable EVSE, remembering to bring it, having it possibly stolen, them not being necessarily weatherproof, etc.)
Neither of the above provide for any access control, billing (if required), time limits, realtime nor near realtime status, alerts, notifications, besides having wear issues w/the outlet and the plethora of different 240 volt outlet types (adding to more confusion). And, there are numerous safety issues w/having 240 volt outlets that would be energized at all times.

A 100D that arrives at this place could take up to 40 hours to fully charge. Ridiculous.
Don't use a level 2 30 amp EVSE then. Use something faster. There are CHAdeMO DC fast chargers on the Chargepoint network besides a ton that aren't on it.
Currently all non-Tesla powered consumer mass-market EVs/PHEVs sold/leased in the US have OBCs that are 7.2 kW or less. 240 volts * 30 amps = 7,200 watts = 7.2 kW
Let's assume it takes 110 kWh from the "wall" to charge a 100D. At 7.2 kW, it would ~15.7 hours, not 40. If it were at 6.2 kW (which would be common the common commercial voltage of 208 volts), it'd take ~17.7 hours.
Nobody at my work commutes from so far away that a 100 kWh car needs to be charged to full to make it home.
NEMA 14-50 can't go higher than a 40 amp continuous load.
