What color is typically used for grounding wires in electrical systems?

In electrical systems, grounding wires are typically colored green or are left as bare copper. This color coding is standardized to help ensure safety and consistency in electrical installations. The purpose of a grounding wire is to provide a safe path for electricity to follow in the event of a fault, helping to prevent electric shock and fire hazards.

Using green or bare copper identifies the grounding wire clearly among other wires, such as those carrying current (which may be black or red) or those that serve specific functions such as neutral (which is typically white). This distinction is crucial for anyone working on electrical systems to ensure they can easily identify which wires are intended for grounding, allowing for safer installations and maintenance.

The other colors mentioned—black, blue, and white—serve different functions in standard wiring systems and do not represent grounding.
