NEC 2023

Categories › NEC 2023

Written by the National Fire Protection Association, the NEC 2023 NFPA 70 is the most recent edition of the NEC to be adopted in the US.

This edition further clarified solar labeling requirements, aligning PV, interconnected power, and energy storage markings. The impact on labeling centered on clearer communication of system state and isolation points, reinforcing the role of permanent, inspection-ready labels in modern solar installations.
