Will a 48-amp Tesla Wall Connector fit on a 200-amp panel?

Updated 2026-11-11. Educational page, not a permit calculation.

Often yes on a 200-amp service, provided the load calculation or measured demand agrees. A 48-amp Tesla Wall Connector (or any 48-amp EVSE) draws 11.52 kW at 240 V and is usually installed on a 60-amp circuit because of the 125% continuous-load rule. That is a large continuous load, but 200 amps is a large service. It is not automatic if the house is already all-electric with backup heat strips.

This page exists because people search the product name. The electrical question is the same as any 48-amp EVSE. On the light all-gas 1,800 ft² example, a 48 A charger calculates to about 77.4 A, which is easy on 200 A. On the heavier combination with a range, dryer example and 10 kVA of heating, it is about 131.4 A — still under 200 A in that simplified walk-through, but worth putting on a real load sheet.

Also confirm the car’s onboard charger: some vehicles cannot draw 48 A, in which case you should not spend the headroom. Use the calculator, and see the 32 A vs 48 A comparison page.

This is not a permit calculation, a utility approval, or a substitute for a licensed electrician, HVAC contractor, or the authority having jurisdiction. Panel Headroom is an independent educational site. It is not a utility, a certification body, or a contractor. Electrical and generator work that is done incorrectly can cause fire, shock, or carbon monoxide poisoning. Use the adopted electrical code and manufacturer instructions; pull permits where required.
