How Many Amps Does a Level 2 EV Charger Use?

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.

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 6 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.

Measure what a Level 2 EV charger actually draws

The figures above are typical ratings, and this load is usually hardwired or on a 240 V circuit, so a plug-in meter can't reach it. A clamp meter reads the current on one conductor at the disconnect or panel without breaking the circuit; opening a panel is work for someone qualified, and the voltage pen confirms a circuit is dead first.
