Completed on June 4, 2026, our Greenville branch installed a new Level 2 EV charging circuit for Duke Energy - Allumia. This project provided a versatile NEMA 14-50 outlet in the garage, giving the homeowner Level 2 charging capability that’s compatible with many portable and wall-mounted EV chargers. The work was performed by our licensed electricians, Johann Fischer and Tyler Harris, and fully permitted in coordination with the Duke Energy program.
Project overview in Greenville, SC
To support reliable Level 2 charging, we installed a dedicated 50-amp circuit from the home’s Eaton CH exterior panel to a NEMA 14-50 receptacle on the left wall of the garage. The cable run was routed cleanly through the crawlspace to keep the garage tidy and maximize charging convenience near the parking area.
Scope of work
- Removed an existing 50A subpanel breaker to prepare space and ensure proper circuit allocation.
- Installed a new, dedicated 50A breaker in the Eaton CH panel for the EV charging circuit.
- Pulled approximately 6/3 NM-B through the crawlspace for a robust 240V, 50-amp feed.
- Mounted and wired a garage-mounted NEMA 14-50 outlet for Level 2 charging flexibility.
- Completed labeling and functional testing to verify correct voltage and safe operation.
- Secured all required permits and documentation for code-compliant installation in Greenville.
This setup gives the homeowner a dependable 240V power source that many EV chargers can use for faster, overnight charging compared to standard 120V outlets.
Why a NEMA 14-50 for Level 2 charging?
A NEMA 14-50 on a dedicated 50-amp circuit is a popular, future-ready option for Level 2 charging. Many EVs and EVSEs can charge at 32–40 amps on this circuit type, significantly reducing charge times while maintaining flexibility if the homeowner upgrades vehicles or charging equipment later. It’s a durable, serviceable solution that balances speed, cost, and compatibility.
Materials and methods used
- Panel integration: Eaton CH exterior panel with a new 50-amp breaker dedicated to EV charging.
- Feeder cable: 6/3 NM-B routed through the crawlspace with secure support and a clean finish.
- Charging receptacle: NEMA 14-50 mounted in the garage for convenient vehicle access.
- Testing and verification: Circuit function and receptacle operation confirmed after installation.
The result is a clean, code-compliant installation that supports reliable daily charging and long-term serviceability.
