Level 2 charger installation
A Level 2 charger runs on a 240-volt circuit, the same kind used by an electric dryer or range. It is the standard way to charge an EV at home overnight.
Level 1 vs. Level 2
Level 1 uses an ordinary 120V outlet and adds only a few miles of range per hour. Level 2 uses a dedicated 240V circuit and can refill most EVs overnight, which is why most owners install one.
What the installation involves
- Site check. The electrician looks at your panel, the charger location and the route for the wire.
- Load calculation. They confirm the panel can carry a new 40–60A circuit, or propose a subpanel, load management or an upgrade.
- Permit. Most cities require an electrical permit for a new 240V circuit.
- Install. New breaker, wire and conduit to the charger spot, then either a NEMA 14-50 outlet or a hardwired connection.
- Inspection and test. The city inspects the work and the electrician tests the charger with your car.
Outlet or hardwired?
A NEMA 14-50 outlet works with plug-in chargers and lets you swap chargers later. Installed cost is usually $700–$1,200. A hardwired charger can run at higher current and suits outdoor spots; it typically costs $1,100–$1,900.
Questions to ask your electrician
- What is your state license number? (Check it on your state's official lookup.)
- Is the permit included in the price?
- What breaker size and wire gauge will you use, and how long is the run?
- Does my panel have capacity, or do I need load management or an upgrade?
- What warranty do you give on the work?
