Which color wire is typically used for ground in most electrical systems?

In most electrical systems, the color green is designated for ground wires. This standard helps ensure safety and consistency in electrical installations, making it easily recognizable for anyone working with or inspecting electrical systems. Ground wires serve a critical purpose: they provide a safe path for electricity to return to the ground in the event of a fault, preventing potential shock hazards and ensuring that excess electrical current is safely dissipated.

The use of green for grounding is consistent across many industry standards, such as the National Electrical Code (NEC) in the United States. This uniformity helps electricians and technicians quickly identify ground connections, which is vital for maintaining safety in electrical installations.
