In a 4-wire Delta system, what color is the high leg typically identified by?

In a 4-wire Delta system, the high leg is typically identified by the color orange. This identification is important for ensuring proper connections and maintaining safety in electrical systems. The high leg, also referred to as the "wild leg," carries a higher voltage and may be at a different potential compared to the other phases.

In many jurisdictions, the use of orange for the high leg aids electricians and technicians in quickly identifying that specific phase, ensuring that precautions are taken during installation and maintenance. This is especially critical in applications where phase rotation and connection integrity are paramount to prevent equipment damage or electrical hazards.

Colors such as red, blue, and green typically correspond to different phases or grounding in electrical systems but do not designate the high leg in this context. Understanding these color codes is essential for anyone working with three-phase power systems.
