At 220 VAC, Level 2 EVSE rated 6.6 kilowatts can supply how much charge current?

At 220 VAC, Level 2 EVSE rated 6.6 kilowatts can supply how much charge current?

• A. 20 A
• B. 30 A
• C. 40 A
• D. 50 A

Answer: (B)

This asks how current relates to power and voltage. The charging power is the product of voltage and current (P = V × I). With a rating of 6.6 kW at 220 V, the current available is I = P / V = 6,600 W / 220 V = 30 A. So the best answer is 30 A. (For reference, at 240 V that same 6.6 kW would be about 27.5 A, but the question uses 220 V.)
