Do I need a permit to install a Level 2 EV charger?

Yes. EV charger installations require a permit in virtually all US jurisdictions. A licensed electrician will pull the permits as part of the installation.

Can I install an EV charger myself?

Technically yes in some states, but it's not recommended. Level 2 chargers require a dedicated 240V circuit, which involves work in your main panel. Mistakes can create fire hazards. Most installers and utilities require professional installation for warranty and net metering purposes.

How long does EV charger installation take?

A straightforward install on a panel with available capacity takes 2–4 hours. If a panel upgrade is needed, add 1–2 days for the upgrade plus 1–4 weeks for utility scheduling.

Quick answer: A 48 A Level 2 charger on a 60 A circuit adds 11.5 kW to your panel load; budget that against your existing 200 A service before installing.

How we calculate EV charger panel load

The calculator estimates your existing panel load from the appliances you select, then checks whether adding the EV charger circuit exceeds your panel's NEC 80% continuous load limit. A 48A EV charger requires a dedicated 60A circuit (48A × 1.25 = 60A).

Required Circuit = Charger Amps × 1.25

If the new circuit would push your total load above panel capacity, the calculator recommends the minimum panel upgrade needed — typically from 100A to 200A service.
