If you own or are considering purchasing an electronic vehicle (EV), then having an electrical vehicle servicing equipment (EVSE) in your home is essential to being charged up and ready to drive. An EVSE is a 240 volt wall-mounted unit with a charging cable that you plug into your vehicle. The cable feeds alternating current (AC) from your home into your vehicle, where your car converts it into direct current (DC) to charge the battery.

When purchasing an EVSE, you should choose one that is rated for 30 amps, so that you can enjoy the luxury of faster charging. A 30 amp EVSE requires a 40 amp breaker for your service panel.
