Home Electrical Wire Selection for EV Charging

Home Electrical Wiring Decision for EV Charging

Overview

When installing an EV car charger facility, the electrical wiring often will be the question a homeowner won't start talking about.

Breaker Amp Wire Gauge (AWG) EV Charger Amp EV Charger Max Power (240V) EV Charger Max Power (230V) EV Charger Max Power (220V)
15A 14 12A 2.88kW 2.76kW 2.64kW
20A 12 16A 3.84kW 3.68kW 3.52kW
30A 10 24A 5.76kW 5.52kW 5.28kW
40A 8 32A 7.68kW 7.36kW 7.04kW
50A 8 40A 9.6kW 9.2kW 8.8kW
60A 6 48A 11.52kW 11.04kW 10.56kW

Normally, for 220V-240V electrical wiring, a 20A circuit breaker is used.  So 12 AWG gauge wire is used inn high power 220V floodlight, electric cloth dryer, air compressor. You can re-wire the existing power outlet to provide 3.84kW (240V) with constant 16A output

Latest Update 2024: Ontario, Canada required EV station to have 50A circuit breaker
