EV Charger Installation in Janesville, WI

What the job is

A Level 2 charger runs on 240 volts, the same as a dryer or a range, on a dedicated circuit from the panel. The electrician sizes the breaker and wire to the charger, runs the circuit to the garage wall or an outdoor post, and either hard-wires the charger or installs a 240-volt receptacle for a plug-in unit. The long part of most jobs is the distance from the panel to where the car parks.

What it costs in Wisconsin

ElectrifyCost's Wisconsin range is $832 to $2,912 (ElectrifyCost). PermitDeck's Milwaukee table puts a Level 2 install at $1,287 to $2,178 (PermitDeck), and a Milwaukee-area contractor lists $800 to $2,500 including permit coordination (its 2026 price guide). Whether the charger hardware is in the number varies by quote, so ask. A panel that has to grow first is a separate line: about $1,500 to $4,500 for 200 amps. All of it is on the cost page.

The permit

Janesville requires a permit for any new wiring or any change to existing wiring (City of Janesville), and state code says no wiring project that adds a branch circuit may start without one (SPS 316.012). An EV circuit is a new branch circuit. A homeowner who owns and lives in the house may pull a branch-circuit permit in Janesville, but if the job touches the service, a licensed Master Electrician pulls it. Fees are in Janesville electrical permits.

Will the panel carry it?

A charger is a large, long-running load, often overnight alongside the furnace, water heater and dryer. On a 100-amp service in an older house that is where the electrician's load calculation earns its fee. The answer is one of three: the circuit fits as is, a load-management device lets it share capacity, or the service gets upgraded. Homes built from 1965 to the mid 1970s may also have aluminum branch wiring worth checking before adding load (aluminum wiring).

The code it is inspected to

Wisconsin adopted the 2023 National Electrical Code effective September 1, 2026 (CR 26-016), so new EV circuits are inspected to that edition, not the 2017 one most online install guides were written for.
