Installing a home EV charger: what you need to know

General home information from Prufloop. Updated October 28, 2026.

The short answer. Level 2 home EV charging needs a dedicated 240-volt circuit sized to the charger, enough spare capacity in your electrical panel, and in most places a permit and inspection. A licensed electrician should do a load check, then install either a hardwired charger or a properly rated outlet. Ask your electric utility about any charger rebates before you buy.

Safety first. Don't run a Level 2 charger on an extension cord or an existing dryer circuit shared with other loads.

What you can safely check

Decide between plugging into a 240-volt outlet or hardwiring the charger. Your car or charger manual lists the amperage it needs.
Look at your panel for open breaker spaces and its main breaker size.
Measure the distance from the panel to where the car parks. Longer runs cost more.
Check your electric utility's website for charger or off-peak rate programs.

When to call a electrician

Always: a new 240-volt circuit should be installed by a licensed electrician

What a electrician will usually do

Runs a load calculation on your panel
Pulls the permit and installs the circuit and charger
Schedules the inspection
Quotes a panel upgrade or load management device if capacity is short

Asking an AI assistant to book it

Once Prufloop launches (planned for Q4 2026 around Charlotte), you'll be able to ask the AI assistant you use something like this, and it can book a verified pro at a posted price in a real open slot. This is how it's planned to work; no assistant is connected yet.

Example request. “I need a Level 2 EV charger installed in my garage in Tega Cay. Book a licensed electrician who handles the permit.”

Before a job is booked, you see the pro's posted price, including any trip or diagnostic fee. Anything extra needs your OK first. When the work is done, you confirm it's fixed with a quick text. That's Proof of Done™.

Questions

Do I need a panel upgrade for an EV charger?

Not always. A load calculation shows whether your panel has room; load management devices can sometimes avoid an upgrade.

Do I need a permit?

In most Charlotte-area jurisdictions, yes. A licensed electrician usually pulls it.

Can my AI assistant book a electrician for this through Prufloop?

Not yet. Prufloop is being built so the AI assistant you already use can book a verified electrician at a posted price, starting with the Charlotte-area pilot planned for Q4 2026 in Mecklenburg, Union, Cabarrus, Iredell, Gaston and Lincoln counties in North Carolina, plus York and Lancaster counties in South Carolina. No AI assistant is connected yet.
