Can your electrical panel handle an EV charger?
It depends on how much power your house already uses. I'm Jason, an electrician. I built ChargeRight to work that out for your house and put it in writing before you pay for a new panel.

- The full NEC Article 220 math
Ask about a car charger, and the first answer you usually get is that you need a new panel. The electrical code's own math adds up what runs on it, like the AC, the dryer, the range and the water heater.
The NEC Article 220 math gives your home credit for how it actually runs, not the worst case your breaker ratings suggest. Like a CarFax for your electrical panel: know its true capacity before anyone bids an upgrade. Why upgrade quotes go wrong|How ChargeRight compares

Straight answers
Do I need a panel upgrade for an EV charger?
Most homes do not. NEC 220.83(A), the load calculation written for an existing home adding a charger, gives credit for how your home actually runs, and a lot of panels have more room than the fast quote assumes. The check tells you whether yours does. If you have a year of utility peak-demand data, an electrician can also check the existing load under NEC 220.87.
What do I receive with the assessment?
A plain-English verdict on whether your panel can take the charger, the exact circuit size your car needs, and the full NEC Article 220 load report with every number behind it - ready to hand your electrician. PDF included.
Is this NEC compliant?
The report runs the NEC Article 220 load calculation that fits your situation. For an existing home adding a charger that is 220.83(A), the section the code wrote for exactly that case. It is the same math a licensed electrician puts on a permit drawing, and the report names the section that produced your verdict. It is a pre-assessment, not a permit or a final electrical design.
Is ChargeRight an electrical contractor or electrician service?
No. I do not bid, schedule, or sell installs, and no contractor pays to be recommended. This is the math, not a sales funnel. No upsell, ever.
How much does ChargeRight cost compared to an electrician?
The assessment is $49.99, one time, on evchargeright.com. No subscription. (Bought inside the iOS app, the same report is $69.99, because of Apple's commission.) The same calculation done in person typically runs $150 to $300 as a service call.
Will my house handle a Level 2 charger?
That is exactly the question the check answers. Pick your car, answer the panel questions, and you get an honest yes or no - with the numbers to back it.
Can my panel handle a Tesla Wall Connector?
On most 200-amp homes, yes. At its full 48 amps the Wall Connector adds 11,520 VA on a 60-amp circuit. Add that to your home's NEC 220.83(A) load and compare the total to your main breaker rating. If it is over, the charger can be set lower, such as 40 or 32 amps, before anyone talks about a panel upgrade. How to check your panel for a Wall Connector
Which NEC section applies to an existing home adding an EV charger?
Normally NEC 220.83(A), when no new heating or air conditioning goes in with the charger. It is the section the code provides for checking whether an existing service has capacity for additional loads. NEC 220.82 is normally used for new construction or a full service change, and 220.83(B) applies when new heating or air conditioning is added too. The NEC 220.83(A) calculation, worked line by line
