- Phase Conductors: Colors will vary depending on the regional standard. Historically these colors were used in North America – Black, Red, and Blue are often used to indicate phases A, B, and C, respectively. Current standards are outlined in NEC (National Electrical Code) and CEC (Canadian Electrical Code).
- Neutral Conductor: Typically white or gray (often indicated with a white or gray stripe).
- Ground Conductor: Usually green or green with a yellow stripe.
- Control Wires: May use a wider variety of colors depending on the specific application.
Consulting the specific system’s documentation and adhering to local electrical codes is always recommended when interpreting wiring diagrams. Understanding the high voltage color code within the diagram allows for accurate and safe execution of tasks.
