The National Fire Protection Association (NFPA) presents updates to the National Electrical Code (NEC) — the foundation for electrical safety in the U.S., once every three years in response to public input. The code is put in place to reduce the risk of fire and other safety hazards. However, it also impacts the way contractors, electricians, specifiers, and other industry professionals plan and execute projects. Therefore, understanding the latest changes is vital.
