If you have never had an EV charger installed, it helps to know what the process looks like. A home charger installation is a straightforward project for a licensed electrician, involving an assessment, running a dedicated circuit, mounting the charger, and passing inspection. Knowing the steps helps you plan and know what a good installation includes.
Here is what to expect during an EV charger installation.
Step 1: Assessment and planning
The process starts with an assessment. The electrician evaluates your electrical panel, confirms it has capacity for the charger with a load calculation, and plans the route from the panel to your chosen charger location. They confirm the charger type and amperage, the wire size, and the breaker needed, and they identify any panel work required. This is also when the permit is arranged.
Step 2: Running the circuit
Next, the electrician runs a new dedicated 240-volt circuit from your panel to the charger location. This involves:
- Installing the correct breaker in the panel
- Running the appropriately sized wire along the planned route
- Fishing wire through walls or running conduit as needed for the specific path
The wire is sized for the charger’s amperage and the distance, following code. If your panel needs an upgrade or load management to support the charger, that is handled as part of the project.
Step 3: Mounting and connecting the charger
With the circuit run, the electrician mounts the charger on the wall at the planned location and connects it. For a hardwired charger, the wiring connects directly to the unit. For a plug-in setup, the electrician installs the 240-volt outlet and the charger plugs into it. The charger is positioned so the cable comfortably reaches your car’s charge port.
Step 4: Permits and inspection
An EV charger installation requires a permit and inspection. The electrician pulls the permit, and after the work is complete, an inspection verifies it meets code. This is an important step that confirms the installation is safe, and it is part of every proper EV charger installation.
Step 5: Testing and setup
Finally, the electrician tests the installation to confirm it works correctly and safely. If you have a smart charger, they may help connect it to Wi-Fi and the app, and configure the charging rate for your circuit. They will also walk you through using the charger so you are ready to plug in.
How long it takes
Many straightforward EV charger installations are completed in a few hours to most of a day, depending on the complexity. A simple run to a nearby location with an adequate panel is faster, while a longer wire run or a panel upgrade adds time. Your electrician can give you an estimate based on your specific situation.
During an EV charger installation, expect an assessment and load calculation, running a new dedicated 240-volt circuit, mounting and connecting the charger, a permit and inspection, and testing and setup. A straightforward installation often takes a few hours to most of a day, with longer runs or panel upgrades adding time. A licensed electrician handles each step to ensure the installation is safe and code-compliant.
