In January, the Board of Electricity approved the 2024 National Electrical Code (NEC).
Significant approved change include:
- Surge Protection Devices (SPDs): All services, including new builds and panel replacements/upgrades, now require a Type 1 or Type 2 SPD to protect electronics from voltage surges.
- Exterior Emergency Disconnects: An external, readily accessible disconnect switch is required for all one- and two-family dwellings, allowing responders to safely shut off power.
- Expanded GFCI/AFCI Protection: The requirement for Ground-Fault Circuit-Interrupter (GFCI) and Arc-Fault Circuit-Interrupter (AFCI) protection is expanded, covering more residential outlets, kitchens, and bathrooms.
- Outdoor/Garage Outlets: There are now more stringent requirements for tamper-resistant and weatherproof outlets in garages and exterior locations.
- Dedicated Circuits & Electrification: Mandates for dedicated circuits are increasing for high-demand equipment, including HVAC systems, water heaters, and electric vehicle (EV) charging stations.
- Arc Flash Labeling (Non-Dwelling): NEC 110.16(B) requires permanent arc flash hazard markings on service and feeder equipment rated 1000 amps or more.
- Code Format Updates: The code includes formatting changes, such as single-column text, modern fonts, and the use of QR codes instead of traditional margin markers to identify changes.
There is currently no timeline for the residential building code to move onto the next stage of rulemaking nor for implementation.
