NFPA 70®: National Electrical Code® (NEC®) is the basis for electrical safety that has saved countless lives.
Adopted in all 50 states, the NEC helps protect people and property from electrical hazards involving wiring and equipment. Comprehensive provisions address electrical installations in virtually all buildings -- including commercial, residential, and industrial occupancies. Revisions to the NEC are industry-driven, based on public proposals and comments. Each editio n of the Code builds on the next, through consensus-based changes that reflect the evolving needs of the field, emerging technologies, and new information about electrical safety.

NFPA®'s Redline PDF contains both the current NFPA document and a Redline version of the document which shows changes from the previous edition marked in color. With the Redline you can quickly spot changed sections and tell specifically what has been changed from the previous edition, saving time and confusion.
