EV charger installation

Level 1 versus Level 2

Most electric cars come with a cord that plugs into a regular 120-volt outlet. That is Level 1, and it adds only a few miles of range per hour. A Level 2 charger uses a dedicated 240-volt circuit, like a dryer, and can refill most cars overnight. For daily driving from a house in Armonk, Level 2 is what most owners want.

What the electrician checks

Before quoting, the electrician looks at:

• Panel capacity, to see whether a new 240-volt circuit fits without an upgrade
• Distance from the panel to the garage or parking spot
• Mounting, on a garage wall, an outside wall or a pedestal by the driveway
• Hardwired or plug-in, depending on the charger and local code
• Permit requirements in your town

EV chargers and generators

If you have or plan a standby generator, think about the charger at the same time. A Level 2 charger is a large load, and running it on generator power can use much of a mid-size unit's capacity. Many installers handle this with load management that pauses charging during an outage, or by keeping the charger off the generator circuits. Tell your electrician about both plans so the panel, transfer switch and charger work together. See whole-home generators.

Detached garages and long runs

Armonk homes often have detached garages or long driveways. Running a circuit underground to a detached garage or a pedestal adds trenching and wire, which Fixr notes can push the installation portion toward $2,000 or more. Ask the electrician to price the route and explain the choice.

Safety and permits

A 240-volt circuit is not a do-it-yourself project. Adding one usually needs a permit and inspection, and the electrician should handle both. Use a charger listed by a recognized testing lab, and follow the manufacturer's installation instructions.
