Do I need a permit for a Level 2 EV charger?
Yes. A 240V circuit installation requires an electrical permit. The work should be done by a licensed electrician.
Do I need to upgrade my panel for an EV charger?
Many homes can support a 40-50 amp EV circuit without a panel upgrade. If your panel is at capacity, you may need an upgrade or a load management device.
Can I install a Level 1 charger without a permit?
Level 1 chargers plug into a standard 120V outlet. If the outlet already exists and meets code, no permit is typically needed. Installing a new dedicated outlet requires an electrical permit.
