A Level 2 charger draws a lot of power — usually a dedicated 240V, 40–60 amp circuit. The big question before installation: does your panel have room?
Start with two numbers
- Your main breaker size: 100, 150, or 200 amps. Look at the largest breaker at the top of the panel.
- Open slots: A 240V charger circuit needs two adjacent open spaces.
A 200-amp panel with open slots is usually an easy yes. A full 100-amp panel often needs help.
What a load calculation tells you
Open slots aren't the whole story. An electrician performs a load calculation — adding up your home's existing demand — to confirm there's headroom for a charger without overloading the service. It's the professional way to avoid tripped breakers and failed inspections.
If your panel is full
You have good options: a 200-amp panel upgrade, or in some cases a smart load-management device that lets the charger share capacity. The right path depends on your home.
