A Level 2 EV charger is one of the best upgrades you can make to a home or business — once. Done right, it charges your vehicle reliably for the next 15+ years. Done wrong, it can overload your panel, melt a 14-50 receptacle, or fail inspection. We install Level 2 EV chargers for homeowners, multi-family properties, and businesses across Fuquay-Varina, Holly Springs, Apex, and Cary.
Most EV owners outgrow Level 1 (the 120V cord that comes with the car) within weeks. Level 1 adds about 3–5 miles of range per hour of charging. If you commute 40+ miles per day, Level 1 won't keep up — you'll wake up to a battery that wasn't fully charged overnight.
Level 2 runs on a dedicated 240V circuit and adds 25–40 miles of range per hour, depending on the charger and the vehicle. A typical Level 2 install fully recharges most EVs overnight from any state of charge. For most drivers, Level 2 is the right call from day one.
DC fast charging (Level 3) is commercial-grade equipment — 480V three-phase, expensive to install, and primarily used for fleet, public, or workplace charging. We handle commercial Level 3 work on a project basis.
Most Level 2 chargers can be either hardwired or plugged into a NEMA 14-50 receptacle. Each has trade-offs:
Most of the cost and most of the engineering happens before the charger goes on the wall:
North Carolina enforces the 2017 NEC (with NC amendments) for one- and two-family dwellings. Article 625 governs EV charging equipment, and these sections drive every install we do:
If you have a 100A panel and you're worried an EV charger means a panel upgrade, there's a code-compliant alternative: an automatic load management system (ALM), sometimes called an energy management system (EMS).
NEC 625.42 explicitly permits this approach. Instead of sizing your service to handle the EV charger plus everything else running at full capacity simultaneously, an ALM monitors your home's real-time electrical usage and automatically reduces — or briefly pauses — EV charging when other large loads (HVAC, electric range, dryer, water heater) are active. When household demand drops, charging resumes at full speed.
The practical impact: a typical 100A home can support a 40A or 48A Level 2 charger without a service upgrade. The trade-off is that charging speed varies based on what else is running, but for most overnight charging this is invisible — the system simply charges the car when the rest of the house is asleep.
Multiple manufacturers make these systems, including the Siemens Inhab Load Manager, DCC-9, Wallbox Power Boost, NeoCharge Smart Splitter, and load-sharing features built into Tesla, ChargePoint, and Emporia chargers. We evaluate which solution fits your panel, your charger choice, and your usage pattern.
Compared to a full 200A service upgrade (often $3,000–$8,000 including utility coordination and required code updates to the rest of the panel), an ALM-based install typically saves homeowners thousands of dollars and avoids the down time of a service swap. It's also reversible — if you upgrade your service later, the ALM hardware can be removed or repurposed.
Load management isn't always the best answer. The right call depends on what else is in the pipeline for your home:
Here's what we typically see without running the full load calculation. This is a starting point, not a substitute for the actual calc:
1. Charger selection guidance — If you haven't picked a charger yet, we'll help you choose based on your vehicle, daily driving needs, and panel capacity. We install all major brands (Tesla Wall Connector, ChargePoint, Wallbox, Emporia, Grizzl-E, Enphase, and others).
2. Site walk and load calculation — We assess your existing panel, run an NEC 220 load calculation, and identify the best route for the new circuit. If your panel is tight, we'll quote both options: a service upgrade and a load management solution per NEC 625.42.
3. Written estimate — Itemized scope, materials, breaker, conductors, receptacle or hardwire connection, permit cost, and any panel work or load management hardware required.
4. Permit and installation — We pull the permit, run the dedicated circuit, install the charger, and test it under load.
5. Inspection — We meet the inspector on site and verify the install passes the first time.
EV charger installation looks simple on paper — one breaker, one wire run, one charger. The complications come from the load calculation, voltage drop on longer runs, panel capacity edge cases, and the decision between a service upgrade and a load management system. Stephen Hobbs-Stone is both a licensed electrician and a licensed professional electrical engineer, which means the install is engineered for the equipment you have today, your home's actual load profile, and whatever EV you buy next.
It depends on three things: how far the charger is from your panel, whether your panel has capacity, and whether you choose hardwired or plug-in. A short run on a panel with open spaces is straightforward. Long runs (50+ feet), full panels needing a sub-panel, or a service upgrade add significant cost. Load management hardware can often replace a service upgrade at a fraction of the price. We provide a written estimate before any work starts.
Yes, in most cases. NEC 625.42 explicitly permits an automatic load management system to limit the EV charging load based on real-time household demand. This lets you install a full-size Level 2 charger on a 100A panel without a service upgrade. The trade-off is that charging speed temporarily reduces when other large loads (HVAC, electric range, dryer) are running. For most overnight charging this is invisible. Whether load management is right for you depends on your other planned upgrades — if you're moving to all-electric heat in the next few years, a service upgrade may be the better long-term investment.
Yes. Any new 240V circuit requires a permit and inspection in Wake County. We handle the permit and inspection.
Most residential installs are completed in one day — typically 4–6 hours on site. Larger jobs (long runs, panel work, or commercial installs) take longer. Permit and inspection scheduling usually adds 1–2 weeks to the overall timeline.
A NEMA 14-50 receptacle limits you to 40A continuous charging. Hardwired chargers can run at the full circuit rating (up to 48A continuous on a 60A circuit). Hardwired is also more reliable for long-term, daily use — receptacle connections can loosen and fail under continuous EV load.
In North Carolina, new 240V branch circuit installations require a permit, and pulling a permit typically requires a licensed electrical contractor. DIY installations also routinely fail because of incorrect conductor sizing, undersized breakers for continuous loads, or panel capacity that wasn't verified — all of which can cause fires.
Yes. We install Tesla Wall Connectors, NACS adapters, and every other major Level 2 brand. The Tesla Wall Connector is hardwired only — there's no plug version — and it can run up to 48A continuous on a 60A circuit. It also has built-in load sharing for installing multiple chargers on one circuit.
Yes. Every modern EV in North America (Tesla, Ford, GM, Hyundai, Kia, Rivian, etc.) is moving to the NACS (Tesla-style) connector, but the hardware on your wall handles the AC power conversion the same way regardless. A properly installed Level 2 charger works with any current or future EV via an adapter if needed.
