As a new electric vehicle (EV) owner, you''ve most likely realized that the Level 1 charger (charging cord) delivered to your car is too slow for daily use and not convenient for travel. But driving to a faster public EV charging station can be
READ MORETypically, Level 2 chargers require a circuit breaker rated for at least 125% of the charger''s maximum current. For instance, if your EV charger has a maximum current of 40 amps, you''ll need a breaker rated for at least 50 amps (40 amps x 1.25 = 50 amps.)
READ MORETypically, Level 2 chargers require a circuit breaker rated for at least 125% of the charger''s maximum current. For instance, if your EV charger has a maximum current of 40 amps, you''ll need a breaker rated
READ MOREFor Level 1 charging, which utilizes a standard household outlet, the common current rating is 12 amps. However, Level 2 charging options, like Tesla Wall Connectors, can deliver higher currents, typically ranging from 40 to 80 amps. Choosing the right wire size depends on the specific charging equipment and its current requirements.

Aluminum Wire Sizing & Ampacity Chart [From 4/0 to 12 AWG] it Is 50 amp wire. 50 amp is a standard breaker size so there is no excuse to use a larger breaker. The supply end breaker must be changed to 50A
READ MOREThe question behind the question is how to size a circuit breaker for an EV charger circuit. I''ve reviewed various sources, and it seems that the breaker could be size at 80% to 125% of the wire capacity, depending on load type. 80% to 125% is a big difference: for 6 awg copper at 90 degrees, it''s a difference between 60 and 90 amps.
READ MOREOr you can also choose 4 AWG and 70 amp ampacity wire. NEC''s 80% rule states that current passing through a wire should not exceed 80% of its current carrying capacity. So, for a 50 amp charger, that would come to 62.5 amps. If one has to account for line losses and voltage drop, then increase this number further by 10%, which is 68.75A.
