how to hardwire ev charger



Are you the proud owner of an electric vehicle (EV)? If so, you may have found that a standard charger just doesn't cut it anymore. To really optimize your charging capabilities, you should consider hardwiring an EV charger in your home or garage. Hardwiring offers several advantages over using a regular power outlet, including faster charging times and increased safety. In this article, we will guide you through the process of how to hardwire an EV charger, ensuring you have a reliable and efficient setup.

Why Choose a Hardwired EV Charger?

A hardwired EV charger provides numerous benefits that can greatly enhance your EV charging experience. Firstly, with a hardwired connection, you eliminate the need for a power cord, reducing clutter and improving safety. Additionally, hardwired chargers offer faster charging times compared to regular outlets, allowing you to charge your vehicle more quickly and conveniently. This is especially beneficial if you have a busy lifestyle and need to get on the road as soon as possible. Furthermore, hardwired EV chargers are more durable and reliable than conventional power cords, ensuring a stable and efficient charging process.

Preparing for the Hardwiring Process

Before you begin the hardwiring process, there are a few things you need to consider and prepare to ensure a smooth installation. Here are some essential steps:

1. Check Local Regulations : Different areas may have specific regulations and codes for EV charger installations. It's crucial to familiarize yourself with these rules to ensure compliance and avoid any legal issues. You may need to consult local building codes or hire a licensed electrician for guidance.

2. Select the Right Charger : There are various EV chargers available on the market, each with different specifications and features. When choosing a charger, consider factors such as charging speed, compatibility with your EV model, and any additional features you may want, like smart connectivity or scheduling options. Research different manufacturers and read customer reviews to find the best charger for your needs.

3. Determine Location : Decide where you want to install the EV charger. Ideally, it should be close to where you park your vehicle. Consider the distance from your electrical panel, as this will affect the installation process. Make sure the chosen location is easily accessible and allows for proper ventilation to prevent overheating.

4. Check Electrical Capacity : Before you begin the installation process, it's essential to assess your home's electrical capacity. Hardwired EV chargers require a dedicated circuit, usually 240-volt, which may necessitate upgrading your electrical panel or wiring. Consult with a certified electrician to verify your electrical system's capacity to handle the new load.

Once you have completed these preparatory steps, you can move on to the actual hardwiring process.

Gathering the Necessary Tools and Materials

Before you begin hardwiring your EV charger, it's crucial to ensure you have all the necessary tools and materials at hand. This will make the installation process easier and more efficient. Here is a list of some essential tools and materials you may need:

1. Wire Cutters and Strippers : These tools are essential for cutting and stripping the necessary wires during installation.

2. Circuit Tester : A circuit tester helps you identify whether a particular electrical circuit is live or not, ensuring your safety during the installation process.

3. Wire Connectors and Electrical Tape : These are required to secure and insulate the wires properly, preventing any potential electrical hazards.

4. Drill and Drill Bits : You might need a drill to create holes for mounting the charger and running the wiring.

5. Metal Conduit and Fittings : If your local electrical code requires it, you may need to install metal conduit and fittings to protect and house the wiring.

6. Wire Nuts, Screws, and Anchors : These are necessary for securing and mounting the electrical components during installation.

7. Voltage Meter : A voltage meter is essential for measuring and testing the electrical current, ensuring the proper functioning of the charger.

Remember to always prioritize safety during the installation process. If you are unsure about any step, it's best to consult a professional electrician to avoid potential risks.

The Hardwiring Process

Now that you have completed the preparatory steps and gathered the necessary tools, let's delve into the actual hardwiring process. Please note that this guide provides a general overview and should not replace professional advice. Consulting a licensed electrician is always recommended for a safe and successful installation. The process typically involves the following steps:

1. Turn off Power : Begin by turning off the power at the electrical panel to ensure your safety during the installation. Locate the circuit breaker that controls the specific outlet or junction box you will be working on and switch it off.

2. Install a Junction Box : If you don't already have an existing junction box near your desired location, you will need to install one. Consult an electrician to determine the appropriate type and size of the junction box required for your installation.

3. Run the Electrical Wiring : Measure the distance from the junction box to the location where you will mount the charger. Using appropriate wiring and conduit, run the electrical wiring from the panel to the junction box. Secure the wiring properly, ensuring it is protected and well-insulated.

4. Mount the Charger : Once the electrical wiring is in place, mount the charger to the desired location following the manufacturer's instructions. Ensure that all mounting screws and anchors are properly secured to avoid any accidents or damage to the charger.

5. Connect the Wires : Strip the ends of the electrical wires you ran earlier, and connect them to the corresponding terminals on the charger. This step requires precision and adherence to the charger's specific wiring diagram. If you are unsure, consult the manufacturer's instructions or seek professional guidance.

6. Test the Connection : After all the wires are connected, double-check the wiring connections to ensure they are secure and correct. Use a circuit tester or voltage meter to test for power. If everything is properly connected, restore the power at the electrical panel and test the charger to confirm its functionality.

7. Secure and Insulate : Once you have verified that the charger is working correctly, secure all the electrical components using wire nuts, electrical tape, and other appropriate fastening materials. This step ensures the safety and longevity of your installation.

8. Conceal and Clean Up the Wiring : Neatly conceal any exposed wiring using conduit, cable clips, or other approved methods, according to local electrical code requirements. Clean up your installation area, removing any debris or unused materials.

Congratulations! With these steps completed, you have successfully hardwired your EV charger.


Hardwiring an EV charger offers numerous advantages over using a standard power outlet. It provides faster charging times, improved safety, and a more efficient and reliable charging experience. Before you begin the hardwiring process, check local regulations, select the right charger, determine the installation location, and assess your electrical capacity. Gather all the necessary tools and materials, ensuring you prioritize safety throughout the installation process. Finally, follow the step-by-step instructions to complete the hardwiring process successfully. Now you can enjoy the convenience of faster and more efficient charging for your electric vehicle.
