What does the color orange typically indicate in electrical wiring?

In electrical wiring, the color orange is generally used to indicate conductors that are intended for specific types of applications, particularly in the context of voltage levels. Specifically, it is commonly associated with high-voltage applications. This means that when you encounter orange wiring, it signifies that the conductor operates at a higher voltage and is designed to handle that increased electrical load safely.

Understanding color coding is crucial for safety and compliance with electrical standards, as it helps electricians quickly identify the purpose and voltage rating of each wire. In many instances, orange may be used for specific types of controlled circuits or for phase identification in three-phase systems. Recognizing that orange indicates high-voltage conductors is essential for ensuring proper connections and preventing accidental contact with wires carrying hazardous voltage levels.

In contrast, other colors have defined roles; for example, typical color coding designates green or bare as ground, white or gray as neutral, and black, red, or blue as hot conductors, which differentiates them from the high-voltage guideline established for orange wires.
