NC Commercial Electrical Code Updates 2026
North Carolina has adopted updated electrical codes affecting commercial properties throughout the state, including businesses in Winston-Salem, Greensboro, and High Point. Whether you're a property owner, business tenant, or property manager, here's what you need to know.
Note: Always consult a licensed NC electrician or your local authority having jurisdiction (AHJ) for requirements specific to your project.
NC's Electrical Code Framework
North Carolina adopts the National Electrical Code (NEC) with state amendments. The current adopted code is based on the 2023 NEC. These requirements apply to: new commercial construction, substantial renovations or tenant build-outs, changes in occupancy type, and additions of new electrical systems or significant loads.
Key Commercial Code Updates Affecting Winston-Salem Businesses
1. EV Charging Infrastructure Requirements
New commercial construction and major renovations must accommodate future EV charging. For new commercial buildings with 5+ parking spaces, conduit pathways and panel capacity must support future EV charger installation.
2. AFCI Protection Expansion
AFCI protection requirements have expanded in commercial settings, particularly for dormitory and hotel-style occupancies. Any renovation or new construction in these occupancy types triggers AFCI requirements.
3. GFCI Protection for Commercial Kitchens
Commercial kitchen requirements have tightened. Dishwashers and equipment within specific distances of sinks now require GFCI protection. Restaurants in Winston-Salem should verify compliance during any kitchen renovation.
4. Surge Protection at Service Entrance
The 2023 NEC requires surge protective devices (SPD) at service entrances for new commercial installations — protecting sensitive commercial equipment from transient voltage spikes.
5. Emergency Lighting Requirements
Updated requirements for emergency lighting duration and battery backup systems apply to commercial renovations. If you're renovating a commercial space in Winston-Salem, emergency lighting must meet current standards.
Common Compliance Issues We Find
- Insufficient circuit capacity for new equipment
- Missing GFCI protection in wet areas
- Emergency lighting that doesn't meet current duration requirements
