What color wiring is typically used for a ground connection?

The use of green or bare wire for ground connections is a standardized practice in electrical installations. Ground wires serve a critical safety function; they provide a path for electrical currents to safely dissipate into the earth in case of a fault, which helps prevent electric shock and equipment damage. The color coding of grounding conductors as green or bare ensures that anyone working on or inspecting electrical systems can easily identify them, which is vital for safety.

In contrast, other colors like red, blue, and yellow are typically used for hot wires or in multi-phase systems, serving different purposes in the electrical circuit design. Recognizing the significance of the color code in wiring helps ensure that installations are performed correctly and safely.
