Unlocking Affordability: The Ultimate Guide to EV Charger Installation Cost at home setup

Due to its convenience, many EV owners or new EV drivers often prefer to charge their cars at home overnight. Installing a high-powered 240V outlet for the charger with the NEMA plug or hardwiring directly to the electrical panel in your garage is the most efficient method. However, many of our customers are curious about the EV charger installation cost at home and what’s needed to do it themselves. In this article, we will cover all the details of the home installation solution and provide you with the materials and design to make it simple.

Home EV charger installation


  • Define your EV charger size and electrical requirements
  • For convenience, install the charger within 10-15ft of the car’s charging port
  • If the charger larger than 50A is not located within 3ft from the electrical panel, install the disconnect switch close to it
  • Ensure to use the proper gauge wire, and don’t forget to properly ground the L2 unit
  • Cheap and reliable home charger

    Consider the following useful steps for EV charger home installation

    Step 1. Collect initial data

    Before initiating the electrical installation and design process, it’s essential to identify the charger type and amperage. For instance, if the unit is rated at 40A, like the Grizzl-E charger mentioned above, this is a 40A unit. Therefore, the AC power coming to the charger from the panel will equal the charging power going to the electric vehicle. Thus, the circuit has to be sized according to the 40A current (plus 20% safety margin that we will cover a bit later). In this case, 8 AWG wire will be the right feet unless your charger located 100ft far from the electrical panel.

    Additionally, it is important to determine how much spare capacity is available on your home electrical panel. Figuring this out yourself can be tricky; therefore, we suggest consulting a local electrician. Many home EV chargers can be manually derated via the dip switch or the rotary dial and even through the app when applicable. Consequently, the wires must be sized according to the derated amperage.

    Step 2. Determine the breaker size

    To make it simple and self-explanatory, we’ve prepared for following table below:

    Charger Type/AmperageWire sizeBreaker size
    Level 2 - 20A charger12 AWG30A
    Level 2 - 24A charger10 AWG30A
    Level 2 - 30A charger10 AWG40A
    Level 2 - 32A charger8 AWG40A
    Level 2 - 40A charger8 AWG50A
    Level 2 - 48A charger6 AWG60A
    Level 2 - 80A charger2 AWG100A

    Please note, the above sizing and recommendations are based on the following parameters:
    1. Distance is no more than 50ft;
    2. Wire type is 90°C (194°F) THWN-2, THHN, XHHW-2, USE-2

    Step 3. EV charger Hardwiring or NEMA plug

    While the NEMA plug is convenient and functions like any other load connected to a residential receptacle, there are certain limitations. Not all EV chargers can use NEMA connectors, especially those larger than 50A, which should be hardwired with an additional disconnect within 3ft. This can certainly raise EV charger installation costs at home.

    Most home EV chargers come with a pre-installed NEMA 14-50P or NEMA 6-50P connector, requiring an appropriate 240V NEMA outlet, respectively. The main difference between the NEMA 6 and 14 is that the NEMA 6 has two hot legs and ground (no neutral), while the NEMA 14 requires four wires (2 hot legs, ground, and neutral).
