Which type of wiring is generally used for ground connections?

The use of green wiring for ground connections is a well-established standard in electrical installations. In the context of electrical wiring color codes, green is universally recognized to signify a ground or earth connection. This designation helps ensure safety and proper function within electrical systems, as it provides a clear indication of which wires are intended to carry no current under normal operating conditions and serve as a path for fault current to enhance safety.

This color-coding standard is particularly important because it assists both beginner and experienced electricians in identifying wires quickly during installation, troubleshooting, and maintenance. By adhering to standard color conventions, the risk of accidental misconnections is reduced, thus enhancing overall safety and reliability of electrical systems.
