Home EV Charging Basics

Charging levels: Level 1 uses a standard 120V outlet and adds only a few miles of range per hour. Level 2 uses 240V and typically adds roughly 20 to 40 miles per hour. DC fast charging is found at public stations and is not a home option.

Circuit sizing: An EV charger is a continuous load, so the circuit is generally sized at 125% of the charger’s amperage. A 40A charger needs a 50A circuit, and a 48A charger needs a 60A circuit. NEC Article 625 covers EV charging equipment in the US.

Before you install: Check your panel capacity, confirm local permit requirements, and use a licensed electrician. Also check state and utility rebates before you buy, since they can offset the cost.
