How Many Amps Does a Level 2 EV Charger Use?
Level 2 EV Charger draws about 40 amps at 240 volts (9,600 watts running). Level 2 EV Charger runs on its own dedicated 240 V circuit — a 9,600 W load calls for at least a 50 A double-pole breaker (your unit's nameplate may require more).
Amps = watts ÷ volts. Enter the wattage from your appliance's nameplate or label for an exact figure.

Breaker figure is guidance for a simple resistive load, sized at 125% for continuous running — confirm against the nameplate and a licensed electrician.
Level 2 EV Charger amperage at 120 V and 240 V
Same 9,600 W load — the current halves when the voltage doubles. Level 2 EV Charger is typically a 240 V appliance in US homes.
| Draw | Watts | Amps at 120 V | Amps at 240 V |
|---|---|---|---|
| Running | 9,600 W | 80 A | 40 A |
Breaker and circuit for a Level 2 EV charger
Level 2 EV Charger runs on its own dedicated 240 V circuit — a 9,600 W load calls for at least a 50 A double-pole breaker (your unit's nameplate may require more). For a dedicated circuit, guidance is a 50 A breaker with 8 AWG copper (75°C terminations) — sized at 125% of the running current because it runs 3+ hours at a time (NEC 210.20).
Guidance only — actual circuit sizing depends on your unit's nameplate, wire run length, and local code. Confirm with a licensed electrician. See the wire & breaker size chart for the full NEC ampacity table.
