Why panel capacity matters
A Level 2 charger adds a meaningful electrical load. The panel must have capacity and safe circuit planning.
Panel readiness
Does Your Electrical Panel Support an EV Charger?
Before installing a Level 2 charger, your electrical panel may need review. Panel capacity, breaker space, charger amperage, and distance to parking can all affect the installation.
Need an installer?
Final scope, pricing, permits, and electrical requirements should be verified by a qualified installer or electrician.
100A vs 200A panel
A 200A panel often has more headroom. A 100A panel may need load management, a lower-amperage charger, or an upgrade.
Level 2 charger load
32A, 40A, and 48A chargers require different circuit sizing and panel review.
Load management
Some homes can avoid or delay a panel upgrade with equipment that manages electrical load.
Subpanel
A subpanel can sometimes organize circuits near the garage or charging location.
When to ask an electrician
Ask for review when the panel is old, 100A, full, unknown, or far from the parking area.
Frequently asked questions
Can a 100 amp panel support a Level 2 EV charger?
Sometimes, but it needs review. A 100 amp panel may require load management, a lower-amperage charger, a subpanel, or a panel upgrade depending on existing electrical loads.
Is a 200 amp panel always ready for EV charging?
No. A 200 amp panel often has more headroom, but breaker space, existing loads, charger amperage, and local requirements still need review.
What is load management for EV charging?
Load management equipment can reduce or pause charging when the home is using too much power, which may help some homes avoid or delay a panel upgrade.
Who should verify panel readiness?
A qualified electrician or EV charger installer should verify panel capacity, circuit sizing, breaker space, permits, and installation requirements.
