What is the standard color for ground wires?

The standard color for ground wires is green and bare. Ground wires are critical for electrical safety, as they provide a path for electric current to return to the ground in case of a fault, thus reducing the risk of electric shock and fire hazards. The use of green for insulated grounding conductors and bare wires (which are typically uninsulated) helps to identify them easily amidst other colored wires.

In electrical systems, adhering to color codes is essential for maintaining safety and ensuring that technicians can quickly and accurately identify the functionality of each wire. This standardized approach aids in preventing confusion and promotes safe practices during installation, maintenance, and repair work.
