Hoschton EV Charger Installation — Home Level 2 Guide

Estimated Read Time: 10 minutes

Level 2 EV charger installation can be a safe, efficient DIY project if you understand code, capacity, and safety. In this guide, you will learn how to plan the circuit, mount the unit, run wiring, and test your charger the right way. We will also show when to stop and call a licensed electrician to protect your home, your vehicle, and your warranty. Atlanta homeowners, read this before you drill a single hole.

Can You Install a Level 2 EV Charger Yourself?

Yes, some homeowners can complete a Level 2 install, but only if the panel has capacity, the run is straightforward, and you understand Georgia’s code requirements. Georgia adopted the 2023 National Electrical Code statewide on January 1, 2025. That change tightened rules for load calculations, GFCI protection, working clearances, and labeling.

DIY is best for simple, in-garage wall mounts near the panel. If your home is older, needs a new circuit, or has aluminum branch wiring, bring in a licensed electrician. Your insurer and EV manufacturer may require permitted, code-compliant work.

"I called Kalahari on a Thursday to get an estimate on a few things, including EV outlet installation... They did a thorough assessment... completed in a timely manner the same day."

Permits, Inspections, and Safety in Georgia

Check with your local jurisdiction before starting. Most Metro Atlanta cities and counties require a permit for a new 240-volt circuit and inspection before energizing. Expect an inspection from the city or county, such as City of Atlanta Office of Buildings or Gwinnett County Building Inspections.

Follow these safety rules from start to finish:

1. Work de-energized. Lock out the panel before touching conductors.
2. Wear eye protection and insulated gloves rated for 600V.
3. Use a listed EVSE and breakers that match your panel brand.
4. Maintain 30 inches width and 36 inches depth of working clearance at the panel.
5. Label the new breaker and EVSE disconnect per code.

Tools and Materials Checklist

Gather everything before you begin. A typical garage install requires:

1. Tools
   • Torque screwdriver with inch-pound scale
   • Non-contact voltage tester and multimeter
   • 7/8 to 1 inch spade bit or hole saw, fish tape
   • Masonry anchors or Tapcons if mounting on block
2. Materials
   • Listed Level 2 EVSE, 32 to 60 amps depending on your vehicle and circuit
   • Correct breaker type, usually 2-pole 40 to 60 amps
   • Copper THHN in EMT conduit or NM-B cable where permitted
   • Appropriately sized conductors by ampacity and distance
   • GFCI protection if required by the EVSE listing or location
   • Dedicated disconnect if EVSE manufacturer requires it

Plan the Circuit: Load, Amps, and Wire Size

Start with your EVSE rating. A common 40-amp charger needs a 50-amp circuit because EV charging is a continuous load. Continuous loads must be sized at 125 percent of the EVSE rating. Examples:

• 32A EVSE → 40A breaker, 8 AWG copper for short runs
• 40A EVSE → 50A breaker, 6 or 8 AWG copper depending on distance and conditions
• 48A EVSE → 60A breaker, 6 AWG copper

Perform a dwelling load calculation using the 2023 NEC method. Consider ranges, dryers, HVAC, and electric water heaters. If your main service is 100 amps and you plan a 60-amp EV circuit, you may exceed capacity. In that case, schedule a panel or service upgrade.

Mounting Location and Cable Management

Choose a spot that avoids tight bends and long runs. Ideal placement is near the garage door or parking spot on a stud wall. Keep the EVSE within the manufacturer’s temperature and height range. Mount to studs or use appropriate anchors. Protect cables from damage and avoid trip hazards.

Tips:

• Keep the total run short to limit voltage drop to 3 percent or less.
• Use conduit for exposed runs. EMT is durable and clean for garage walls.
• If outdoors, use NEMA 3R or 4-rated equipment and wet-location fittings.

Step-by-Step Installation Overview

1. De-energize and lock out the panel.
2. Confirm panel space and install a listed 2-pole breaker sized for the EVSE.
3. Mount the EVSE backplate per the template. Verify plumb and stud engagement.
4. Route conduit or cable from panel to EVSE. Support within code spacing rules.
5. Pull conductors. Typical pulls include two hots and a ground. Many EVSE units do not require a neutral. Follow manufacturer instructions.
6. Terminate conductors at the breaker and EVSE lugs. Torque to specification.
7. Add GFCI protection if required by the EVSE listing or by location.
8. Label the breaker and the EVSE disconnect. Update panel directory.
9. Restore power, then commission and test.

Testing and Commissioning

Before plugging in your vehicle, verify the following with a multimeter:

1. Correct voltage at the EVSE terminals.
2. Proper grounding and polarity.
3. Breaker trips as designed when pressing the test button if GFCI is present.
4. EVSE status lights show ready state. Run the manufacturer’s self-test.
5. Start a charging session at low current. Monitor heat and verify stable operation for at least 15 minutes.

"What a great experience. Last minute call to remove a 220 EV car charger. They were great and fast."

Common Pitfalls and How to Avoid Them

• Undersized wire. Long runs need upsized conductors to limit voltage drop.
• Wrong breaker type. Panels require brand-specific breakers to maintain listing.
• Shared circuits. EVSE requires a dedicated circuit, not a tandem or shared load.
• Skipping permits. Many policies can deny claims if unpermitted work causes a loss.
• No surge protection. A whole-house surge protector can protect sensitive EVSE electronics from summer thunderstorm surges common in Metro Atlanta.

If you encounter aluminum branch wiring, Federal Pacific or Zinsco panels, corrosion, or a crowded bus, stop and consult a licensed electrician.

When You Need a Panel or Service Upgrade

EV charging adds a large continuous load. Signs you need an upgrade:

1. Main service is 100 amps with electric range, dryer, and heat pump already on the system.
2. The panel is full or uses undocumented tandem breakers.
3. You need a 60-amp circuit for a 48-amp EVSE and the calculation exceeds service capacity.

Outdoor vs. Garage Installs

Outdoor installs must consider weather, UV, and physical damage. Use NEMA 3R or 4 enclosures, wet-location wire methods, and in-use covers. Provide clear working space and a listed disconnect within sight if required by the EVSE manufacturer.

Garage installs are simpler but still need protection from vehicle impact. Mount above bumper height and use guards if needed. Always follow the EVSE manual and local amendments.

Costs, Rebates, and Timelines in Metro Atlanta

Typical costs vary by distance from panel, wall type, and amperage:

• Simple garage run near the panel: generally the least costly and fastest, often completed same day.
• Longer conduit runs, masonry drilling, or outdoor posts increase labor.
• Panel upgrades add parts and permit time.

Rebates and incentives that can reduce your net cost:

• Georgia Power offers a Level 2 EV charger rebate, commonly cited as $150 when installed by a licensed electrician. Program terms can change. Confirm current details on the utility site.
• Cobb EMC and other local utilities provide additional rebates for EV chargers and energy upgrades.

Inspections are typically scheduled within 1 to 3 business days in cities like Lawrenceville, Alpharetta, and Marietta. Same-day service is often available for straightforward installs.

DIY vs. Pro: How to Decide

Choose DIY if you have panel capacity, permit clarity, and comfort with 240-volt circuits. Choose a pro if you need any of the following:

1. Load calculation or service upgrade
2. Long or complex conduit runs
3. Outdoor pedestal or detached structure wiring
4. Bonding, grounding, or GFCI questions
5. Fast turnaround with documented, permitted work
