Green or Green with a yellow stripe: The earth wire, also known as the ground wire, is usually colours-coded green or green with a yellow stripe (revamped), and this unique color combination is internationally recognized as the standard color for identifying grounding. Let's say you cut your cable and see this series of colors: black, white, red, green, orange, and blue, in that order and in a consistent pattern. This is an E-1 color code (formerly known as a K-1 code) because it includes both a white and green conductor. As a result, this tray cable may not work. To reduce mistakes during choosing a specific cable tray at the time of cable pulling, it's suggested to paint both ends of each cable tray line with ordinary paint. For example: - power electric cable: black color, - Fire&Gas cable: red color, - Instrumentation and control system cable: blue. The color coding of cables is not a random aesthetic choice; it is a critical safety language. Note: The colours in a NYM cable also follow this scheme exactly. In complex systems, electricians and technicians need to distinguish between power, control, and signal circuits instantly.
