EV Sizing FAQ for Tesla Model X

What breaker size and wire gauge do I need for a Tesla Model X Level 2 charger?

With a 11.5 kW onboard AC charger (48A continuous load at 240V), NEC Section 625.41 requires sizing the branch circuit at 125% of continuous load: a 60A double-pole breaker with #6 AWG THHN copper wire in conduit (or #4 AWG NM-B Romex where permitted by code).

How long does it take to recharge a Tesla Model X for a 40-mile daily commute?

At 3.3 miles per kWh, a 40-mile daily commute uses approximately 12.1 kWh. At 11.5 kW Level 2 AC output, replenishing 40 miles takes roughly 1.05 hours.

Can I use a NEMA 14-50 plug-in outlet for my Tesla Model X instead of hardwiring?

While an EV-rated NEMA 14-50 receptacle supports up to 40A continuous charging (9.6 kW) on a 50A breaker, hardwiring on a 60A circuit is required under NEC 625.41 to deliver full 48A (11.5 kW) charging.
