National Electrical Code


Everyone knows that the National Electrical Code® (NEC) is the preeminent electrical installation code in the U.S. However, the NEC takes on real significance when it is adopted into law by states and local jurisdictions. The timing for adoption of installation codes is different by locals, and some locals adopt the NEC with state or local amendments. The result is that different electrical codes are being enforced in different parts of the U.S.

NEMA's Field Representatives track the adoption of the NEC in their respective territories and have developed a report that identifies which electrical codes are enforced where.
