In building electrical wiring systems, the ground wire is normally:

Explanation:
Ground wires are colored green to identify them as the equipment grounding conductor. This conductor provides a safe, low-impedance path to earth for fault currents, which helps tripping of overcurrent protection and reduces the risk of shock. The NEC specifies green (or green with a yellow stripe) for grounding conductors to distinguish them from hot conductors (black or red) and the neutral (white). Bare copper can also serve as ground in some installations, but green insulation is the standard in modern wiring. Hot conductors carry current during normal operation, and the neutral returns current; neither should be confused with the grounding path.
