Wire Color Coding




--------------------------------------------------------------------------------

This page describes wire color coding as defined by current military specifications. The color coding is used on the wiring insulation.
Wire color coding is used to indicate wire function or the voltages the wire carries.
The NATIONAL Electrical Code [NEC] requires their own coding SYSTEM for premises wiring.
The NATIONAL Fire Protection Association [NFPA]; specifies wire insulation colors for industrial machinery [machine tools].
These color codes may or may not apply to your specific application, because they apply to Drills, Motors, and so on. The NFPA color scheme uses a solid color with another color strip for a NUMBER of applications.
NFPA color codes differ from NEC and Mil STANDARD wire codes. For details, see: NFPA 79: Electrical STANDARD for Industrial Machinery.
