For service and feeder calculations, EVSE load shall be calculated at either 7200 VA or the nameplate rating of the equipment, whichever is larger.

For service and feeder calculations, EVSE load shall be calculated at either 7200 VA or the nameplate rating of the equipment, whichever is larger.

• A. 1500 VA
• B. 3000 VA
• C. 5800 VA
• D. 7200 VA

Answer: (D)

When sizing service and feeders for EV charging, you use the larger of the EVSE’s nameplate rating or a fixed minimum of 7,200 VA. This 7.2 kVA minimum acts as a conservative baseline to ensure the installation can handle the charging load, since EV charging can draw substantial power and variability exists in how devices are used. 7,200 VA corresponds to about 30 A at 240 V, a common Level 2 charging level, which helps standardize calculations across different equipment. In the scenarios given, each nameplate rating is below 7,200 VA, so the load is taken as 7,200 VA. If the nameplate rating were higher than 7,200 VA, you would use that higher rating instead.
