What are the common safety colors used in electrical wiring?

The common safety colors used in electrical wiring are recognized for their clarity in indicating the function of different wires within an electrical system. The correct answer details that black and red are used for live wires, white is designated for neutral wires, and green or bare wires are used for grounding.

This color coding is essential for safety and proper identification. The use of black and red for live wires helps electricians and maintenance personnel easily understand which wires carry current, reducing the risk of accidental shocks or short circuits. White indicates a neutral wire, which serves to return current and is typically at ground potential. Ground wires are critical for safety, as they provide a path for fault current to prevent electric shock. The color green or bare wire signifies that it is dedicated to grounding, which is necessary for the protection of both equipment and personnel.

In practical applications, adherence to these color codes is essential, as it ensures consistency in installations and repairs across the industry, facilitating both safety and efficiency.
