EV charger installation

Why Level 2

The cord that comes with most electric cars plugs into a standard 120-volt outlet. That is Level 1, and it is slow. A Level 2 charger runs on 240 volts, like a dryer or range, and charges many times faster. For daily commuting from Harrison, most owners find Level 2 is the practical choice.

What the electrician checks

Before quoting, expect questions and a look at:

• Panel space and capacity for a new 240-volt circuit
• Distance from the panel to the charger spot
• Mounting in the garage, on an outside wall or on a pedestal
• Hardwired or plug-in connection
• Permit needs for your village or town

Planning with a generator

A Level 2 charger is one of the biggest loads in a house. If you have a standby generator or plan one, decide how the charger will behave during an outage. Many installers use load management to pause charging while on generator power, or keep the charger off the generator side. Planning both together keeps the generator from being overloaded. See standby generator installation.

When costs go up

The price rises when the panel needs an upgrade, when the circuit has to run a long way, or when it must go underground to a detached garage or pedestal. Ask the electrician to explain the route they chose and the alternatives.

Safety and permits

Installing a 240-volt circuit is licensed electrical work, not a do-it-yourself job. Most towns require a permit and inspection. Choose a charger listed by a recognized testing lab and follow the manufacturer's instructions.

Choosing a charger

Most Level 2 chargers sold for homes work with most electric cars, using an adapter where needed. Look at the maximum charging rate your car accepts, the cable length you need to reach the charge port from where you park, and whether you want app controls or scheduled charging. Scheduled charging can help you plan around time-of-use rates if your utility offers them. The electrician sizes the circuit to match the charger you choose.
