What color must insulated conductors of number 6 or smaller be if intended for use as ground conductors?

Insulated conductors intended for use as ground conductors must be identifiable to ensure safety and compliance with electrical codes. The standard color codes specify that ground conductors should be green, or if insulated, they can also be green with one or more yellow stripes. White or gray conductors, or those with three white stripes, are also permitted provided they are used in a manner that does not create confusion with other functions, particularly the neutral conductor.

The choice of white or gray for certain low-voltage applications as an additional identifier helps to differentiate them from other conductors, ensuring that technicians and electricians can easily distinguish ground conductors from live conductors. This identification plays a crucial role in maintaining safety protocols and preventing electrical hazards.

Understanding this guideline is essential for anyone involved in the installation and maintenance of low-voltage special systems, as incorrectly identifying ground conductors could lead to hazardous situations and non-compliance with regulations.
