NATIONAL ELECTRICAL CODE NFPA 70
The purpose of the NEC is for the protection of persons and property. The NEC is for safety. The NEC
is not intended as a design specification or an instruction manual for untrained persons. The NEC
covers most electrical installations, but not all. The NEC does not cover cars, trucks, boats, ships,
planes, underground mines, trains, utility controlled communication equipment, and utility power distribution
locations. The NEC does cover commercial parking lot lighting installed by the electric utility on
private property. The NEC is divided into an Introduction and nine Chapters. Product evaluation is
done by nationally recognized independent testing laboratories, not the electrical inspector. The
authority having jurisdiction approves the use of products and enforces the requirements of the NEC,
but they can't make up their own rules. Mandatory rules use the word shall. Explanatory material is
contained in the Fine Print Notes (FPN).
