I am sure Lawrence is talking about his 2016 Leaf with 30kWh (not kW) pack. Since it is a newer Leaf, it will charge at 6.6kW instead of the 3.3 that the 2011/2012 Leaf takes (which is specifically aimed at the European situation where most plugs and circuits are rated and fused to 230V 16A which means a max 3.7kW so a 3.3kW charger maxes out a standard wall plug in Europe). 6.6kW at 240V is 27.5 Amps so it is even too much for a 30A service as continuous load although the standard 24kWh Leaf pack usually does not take more than 18kWh to fully recharge, so less than 3 hours which means that you could sneak by the 80% derating for continuous load by never charging long enough to get hit by that limit and you can cosy up to the 100% rating for the circuit. Note that an EVSE destined for a 30A service will limit the current at 24A by modulating the Pilot signal and thus forcing the EV to never draw more than 24A x 240V = 5760W. Only a 40A (or 50A) circuit will allow an EVSE to supply the full power that a newer Leaf can draw by modulating the Pilot signal to allow drawing 32 (or 40) Amps.

I take it this is 240v, so you have a 125 amp breaker? That's what you would need to deliver 30kw. I assume that's wired directly to the EVSE. Heck of a cable! But what EVSE can supply 125 amps?
