What green wire in electrical systems typically signifies?

The green wire in electrical systems is commonly associated with grounding. Grounding wires provide a safe pathway for electricity to flow back to the ground in case of a fault or short circuit. This is essential for preventing electrical shock and ensuring the safety of both people and equipment. Grounding helps protect electrical systems from surges and also stabilizes voltage levels.

In most electrical codes, the use of green for grounding is standardized to help prevent accidental connections and promote clear identification of electrical components for maintenance and safety. This distinct color coding plays a critical role in ensuring that anyone working on or with the electrical systems can easily recognize the purpose of each wire, minimizing risks associated with incorrect handling.
