I have a client that wants (2) 240 Volt, 32 Amp, 1-phase EV chargers installed on their residential property. Does the NEC allow me to run a 240 Volt, 100 Amp feeder to power both chargers without having to have any additional overcurrent protection?
 
There would be 3 problems with the EV chargers I have seen:
1. The have been marked with a max OCP
2 The terminals will not accept a #2
3 The disconenct must be readily accessible.
 
Thank you all for the wonderful info. These are fixed-in-place, hard-wired to a junction box, so no mechanical lug size limitations, nor GFCI requirements, however the disconnect requirement is valid. Not sure, about the sub-panel. The point of the question is to see if we can get away from any subsequent over current protection and rely only on the 100A breaker. I haven't seen a maximum size for the OCP shown on the nameplate, only a minimum of 40 Amps.

What brand are they? The only hard-wired 32A EVSE I am familiar with is Enphase, and their installation instructions require a 40A breaker.

The real question is whether one charger may be supplied by a 100a circuit.

I don’t think there’s anything in NEC article 625 that precludes it specifically. But things like manufacturer’s instructions, termination of wires that may be too large for the lugs, etc. come into play.
