Overview
A Level 2 charger runs on a dedicated 240-volt circuit and can charge most EVs overnight. Installation usually means running a new circuit from your panel to the garage or driveway.
The biggest variable is whether your panel has capacity. If it doesn't, options include load management devices or a service upgrade.
What to expect, step by step
- Choose a location. Distance from the panel affects wire runs and cost.
- The electrician sizes the circuit. Charger amperage determines wire and breaker size.
- Hardwired or plug-in. Some chargers plug into a 240V outlet, others are hardwired.
- Start with a description of the problem. Note which circuits, outlets or fixtures are affected and when it started.
- Expect an on-site look. Most electrical work begins with an inspection of the panel, wiring and the area involved.
- Permits are common. Many jurisdictions require a permit and inspection for new circuits, panel work and service changes.
Before you decide
- Outdoor installs need weather-rated gear. Exterior chargers and conduit must be rated for outdoor use.
- Access affects price. Finished walls, attics and crawl spaces change how much time running new wire takes.
- Capacity matters. Adding big loads like EV chargers, hot tubs or heat pumps can exceed what the existing service supports.
- Panel capacity drives cost. A panel upgrade can add significantly to the project.
- Rebates may apply. Utilities and governments sometimes offer EV charger rebates.
- Older wiring changes the job. Homes with aluminum branch wiring, ungrounded outlets or fuse panels may need extra work.
What to have ready
- Your address or nearest cross streets so the request reaches someone local.
- Rough measurements or quantities, if they matter for the job.
- The best way and time to reach you.
- Your timeline, and whether anything is urgent.
- Photos, if you have them; they help a provider understand the job faster.
Warning signs
- Requests for large cash deposits before any work is scheduled.
- Door-to-door offers right after a storm with no local track record.
- Suggesting you skip a required permit to save money.
- Pressure to sign or pay the same day.
- No written estimate, or an estimate with vague scope.
Questions worth asking
- Are you licensed for electrical work in this jurisdiction, and will you pull the permit?
- Is the estimate written, and does it list materials, labor and permit fees separately?
- Who will do the work, and will they be licensed or supervised by a licensed electrician?
- What warranty do you offer on labor and parts?
- How will you protect finished areas and clean up afterward?
- Is a final inspection included, and who schedules it?
Frequently asked
- Can I use a regular outlet?
- A standard 120V outlet works for Level 1 charging, but it's slow. Most owners prefer Level 2.
- How long does installation take?
- Simple installs are often done in a few hours, while longer wire runs or panel work take longer.
- Can I do my own electrical work?
- Rules vary by state and city. Many places allow limited homeowner work with a permit, but service and panel work is usually best left to a licensed electrician.
