According to electrical standards, what is the color code for the ground wire?

The color code for the ground wire is green. This standard is widely recognized in electrical wiring practices and is crucial for safety. The purpose of the ground wire is to provide a safe path for electrical current to return to the ground in case of a fault, helping to prevent electrical shock and equipment damage.

Using a consistent color, like green, for ground wires helps ensure that electricians, technicians, and anyone involved in electrical work can quickly identify the ground wire among other wires in a system. This identification is vital during installations, repairs, or troubleshooting, where proper grounding can mean the difference between safety and danger.

While other colors like black, blue, and yellow are used for different phases or types of wires (like hot wires or signal wires), they do not indicate grounding. Therefore, adhering to the standard color code for ground wires is critical in maintaining safety and compliance with electrical codes.
