How to use color coding for wiring in a distribution box
This guide describes wiring color codes, international standards, and main rules to keep in mind to work smarter and safer. The standard electrical wire color code mandated by the National Electrical Code (NEC) is a critical safety system for licensed electricians. For typical building AC circuits (commonly up to 600 volts nominal), the NEC specifies identification rules for grounded conductors (neutral), requirements. The table below gives a quick snapshot of the most common electrical wire colors you can see at home. This is a general reference, not a substitute for proper testing. They make it easy to identify immediately which wires are live, neutral, or grounded (avoiding costly mistakes and hazardous accidents)., including the use of color-coded wiring.
