Which wire color is commonly associated with the ground in residential wiring?

In residential wiring, the color green or bare is commonly associated with the ground wire. Ground wires are essential for safety, as they provide a path for electrical current to return to the ground in the event of a fault or short circuit. This helps prevent electrical shock and protects equipment from damage.

The use of green insulation or a bare wire (which has no insulation) signifies its unique function within the electrical system. This color-coding standard is established to enhance safety and prevent confusion during installation and maintenance of electrical wiring. By clearly distinguishing the ground wire with these specific colors, electricians and technicians can quickly identify which wire is intended for grounding purposes, thereby promoting safe practices in electrical work.
