You need to look at the breaker to see how many amps the garage 240 circuit can handle. Then multiply that by .8 to get the amount of continuous load it can handle. If it is a 30 amp circuit, then you should NOT use the Nissan dual voltage EVSE on it, because the car will draw 27.5 amps - too much for continuous use. If the circuit is 50 (or 40) amps then you can have the correct plug installed in the outlet.
