Installing a Level 2 electric vehicle (EV) charger at home is a key step for EV owners who want faster, more convenient charging without relying solely on public stations or slower level 1 charging. In this article, we’ll walk through all of the important information you need about a level 2 charger installation, including why they’re beneficial and what steps are involved. While we always recommend that the actual installation be handled by a licensed professional, this guide will help you make informed decisions and understand what to expect when setting up your home charging solution.
What is a Level 2 EV Charger?
A Level 2 EV charger is a significant step up compared to the standard Level 1 chargers that come with most EVs. While Level 1 chargers plug into a regular 120-volt outlet and can take up to 20+ hours to fully charge your vehicle, Level 2 chargers use a 240-volt outlet and can reduce charging time to just 4-8 hours. It’s a faster, more efficient option for EV owners who rely on daily charging.
These chargers require dedicated electrical infrastructure capable of handling a 240-volt circuit, which is why installation often involves planning and professional assistance.
Can You Install a Level 2 Charger Yourself?
Here’s the short answer: It depends on your electrical skills. While it’s technically possible to install a Level 2 charger yourself (especially if you already have a NEMA plug installed), it isn’t always the safest or most practical option.
Why you should be careful with a DIY installation
Level 2 chargers use high voltage, which can be dangerous. Aside from risking injury to yourself, errors during setup could damage your charger or EV and might even void your warranty. Additionally, many areas require permits and inspections for installation, and professionals are well-equipped to handle these steps properly.
Unless you have extensive experience with electrical work, hiring a licensed electrician is the safest and most efficient choice for most homeowners. At Emporia, we recommend most people work with a professional installer or electrician – and we can help get you set up with a high-quality, trustworthy contractor.
Why you should work with a licensed electrician
A licensed electrician isn’t just someone who hooks up the wires. They bring expertise and knowledge of local electrical codes, ensuring your setup is safe, reliable, and compliant. Here’s why it’s worth consulting a professional for your Level 2 charger installation:
- Safe installation: Electricians are the safest choice for installing your EV charger. They ensure everything is set up correctly, so you don’t have to worry about mistakes or safety risks.
- Electrical inspection: An electrician will evaluate your home’s electrical capacity to confirm if it can handle a 240-volt circuit without overloading your breaker box.
- Permit and code compliance: Most areas require permits for EV charger installations. A certified electrician will secure these permits on your behalf and handle inspections to make sure your setup is compliant and safe.

Step-by-Step Guide to Installing a Level 2 EV Charger at Home
If you’ve decided to take the plunge into installation mode (whether hiring help or tackling it solo), this step-by-step guide outlines the key phases of the process.
Step 1: Assess your home’s needs and electrical capacity
Start by confirming whether your home can support a 240-volt circuit. Check if you have:
- Enough capacity in your electrical service panel (commonly referred to as a breaker box).
- Headroom for additional load without causing electrical issues.
If you’re unsure, always consult a professional to evaluate your home’s capacity.
Step 2: Choose a location for installation
Strategically pick a spot where your Level 2 charger will be both accessible and functional. You’ll need to consider:
- Distance to your EV: Shorter distances reduce the need for long cables, minimizing power loss and tripping hazards.
- Indoors or outdoors: Make sure outdoor installations have weatherproof protection.
- Flexibility for future needs: If you have multiple cars or parking arrangements, choose a spot that accommodates potential growth.
Step 3: Get an electrical permit
Local regulations almost always require you to secure an electrical permit before installation. If you’re hiring an electrician, they will typically handle this step for you.
Step 4: Mount the charger hardware
Mount your EV charger securely to the spot on the wall you’ve chosen. Ensure that:
- It’s placed at a comfortable height for easy access to the charging cable.
- The surface is sturdy enough to hold the unit over time.
- Screws and brackets are tightened to prevent movement or damage.
Step 5: Electrical work
This critical step varies based on whether your charger is plug-in (uses a NEMA outlet) or hardwired:
- Plug-in charger: If you’re using a NEMA 14-50 outlet, installation is straightforward once the outlet is installed by an electrician: you simply need to plug your charger into the socket.
- Hardwired charger: Hardwiring an EV charger requires connecting directly into your home’s electrical system. This step should only be done by licensed professionals.
If you’re doing this part yourself, be sure to turn off the electricity at your main breaker before starting to avoid any risk of shock, and wear insulated gloves for added protection. To access the necessary wiring, you’ll need to carefully remove the breaker box cover. Depending on your setup, you may also need to install a junction box to manage and connect the wiring properly. Always double-check all connections and strongly consider consulting a licensed electrician if you are unsure about any steps.
How Much Does Level 2 Installation Cost?
Installation costs can vary depending on several factors:
- Location: Regional differences in contractor rates and permitting fees.
- Installation complexity: Distance from the electrical panel to the charger location (longer distances often require extra conduit, driving costs up).
- Permit and inspection fees: Prices vary by area but are mandatory for legal installation.
- Custom work: Older homes may require breaker box upgrades or modifications.
On average, the total cost ranges between $500-$2,500, including the charger itself, permitting, and professional installation.
