Wire color: The neutral wire is blue, and the color of the phase wire (A phase is yellow, B phase is green, and C phase is red) should meet the standard. Wire specification: Select the appropriate wire specification according to the circuit load. WARNING: Please be aware that the table below is a guide; a wire should never be identified by color alone. Wire color helps identify intent, not actual condition. Before handling any wire, always rely on testing with professional tools, not assumptions. Testing is the only reliable way to confirm. This guide describes wiring color codes, international standards, and main rules to keep in mind to work smarter and safer. The various colored wires that you can see when you look behind a switch or an outlet are not an accident, but rather a safety feature that is built in. For typical building AC circuits (commonly up to 600 volts nominal), the NEC specifies identification rules for grounded conductors (neutral), requirements. Electrical wiring color codes are a standardized system that tells electricians—and you—the specific job of every wire in the circuit. Getting this language right is the difference between a light that works and a dangerous situation involving short circuits, electrical shocks, or even fires. These color codes are used for electrical distribution systems, and while some are mandatory, others are optional. The lighting and socket circuits generally use.
