As electric vehicles (EVs) become more common on North Carolina roads, more homeowners are choosing the convenience of at-home charging. But before you install a Level 2 charger, it’s important to understand state and local requirements for permits, electrical capacity, and proper placement so your installation is safe, compliant, and future-proof.
What Chargers Are Most Homeowners Installing?
Most homeowners opt for a Level 2 charger (240 volts) for home installation because it can add significantly more range per hour than a standard wall outlet (Level 1), making overnight charging practical for daily use. Level 1 chargers (120 V) are slow and best only for occasional top-ups.
When Is a Permit Required?
In North Carolina—as in most states—permits are required when you install a new EV charging circuit or make significant electrical upgrades. This includes running a dedicated circuit from your home’s electrical panel or adding a new outlet for a Level 2 charger.
- Electrical permit: Usually required for any changes to home wiring.
Panel Capacity & Circuit Requirements
Before installation, an electrician will assess your electrical panel to determine whether it can support the new charger. Most Level 2 chargers need:
- A dedicated 208/240 V circuit
- 40 amps or more of capacity (common in modern Level 2 setups)
If your panel is older or near capacity, you may need an upgrade, such as a subpanel or increased service size, to safely power the new charger.
Where Can You Install an EV Charger?
Garage Installations
Chargers can be mounted on the garage wall at a height that avoids vehicle bumping.
Outdoor Installations
Outdoor chargers must be weatherproof and often require protective measures like bollards or curb stops to prevent damage from vehicles. Adequate lighting near the charging area is recommended for safety and convenience.
