NEC Editions: Where Nashville Stands and Where It’s Headed

Every three years, the National Fire Protection Association officially updates the National Electrical Code. Nashville’s Metropolitan Council officially adopted the 2023 NEC (alongside the 2024 International Codes) on July 15, 2025, bringing modern safety and efficiency standards to every residential and commercial project. The next NEC update will arrive in 2026, but as for now, Tennessee residents only need to worry about the updates detailed below:

New GFCI Requirements to be Enforced

The 2023 NEC expands ground-fault circuit interrupter (GFCI) protection beyond countertop receptacles to all kitchen outlets, laundry areas, and outdoor receptacles. All 125 V to 250 V receptacles in any damp areas, including bathrooms, must implement GFCI protection. This dramatically reduces shock hazards in high-moisture environments. These changes mean that any time an electrician adds or replaces outlets in these zones, GFCI protection must be incorporated. This not only safeguards occupants but also aligns your property with Nashville’s latest safety mandates.

Schedule a comprehensive GFCI upgrade with Jarrett Companies to keep your kitchen and exterior outlets fully protected.

Expanding AFCI and Surge Protection Standards

Arc-fault circuit interrupter (AFCI) requirements have also broadened, now covering living rooms, bedrooms, dining areas, and other areas where electrical fires typically originate.. At the service entrance, the 2023 NEC mandates surge protective devices (SPDs) to shield sensitive electronics from damaging voltage spikes and arc faults. By installing SPDs and AFCIs, licensed electricians not only bring your property up to code but also extend the life of equipment and lower insurance premiums by demonstrating enhanced fire and surge mitigation.

Solar PV Rapid Shutdown Clarifications

For properties with photovoltaic (PV) systems, the 2023 NEC clarifies rapid shutdown requirements. This clarification does not include PV installations on non-enclosed, detached structures like carports. This revision simplifies compliance for solar-equipped properties: electricians can more efficiently design and install safety disconnects without redundant equipment on detached canopies or trellises. 

If you’re integrating or upgrading solar PV, trust Jarrett Companies to keep your Nashville property both green and code-compliant. Visit our website or call 615-515-1270 for a comprehensive inspection. 

Grounding and Bonding

Proper grounding and bonding are foundational to any safe electrical system. NEC Article 250 spells out conductor sizing, grounding electrode requirements, and bonding jumpers to ensure fault currents have a clear path back to the service equipment. Licensed electricians follow these rules to:

  • Prevent shock hazards by equalizing potential between exposed metal parts and earth.
  • Maintain stable neutral-to-ground connections for surge and lightning protection.
  • Comply with stricter grounding electrode conductor sizing in new installations.
