What is the CT wiring color code for 120/208?

The wiring color code for a 120/208 volt system utilizes specific colors to designate different phases and the neutral. In this configuration, the standard colors are black for phase A, red for phase B, and blue for phase C, with white typically being used for the neutral wire. This allows for clear identification of each phase in the three-phase system, which is essential for safety and proper functionality.

Choosing blue for phase C is particularly significant because it helps distinguish it from the other phases, especially in systems where installations may involve multiple types of wiring configurations. This color coding ensures that electricians can safely and easily identify which wires correspond to which phases during installation, troubleshooting, or maintenance.

The other options do not reflect the standard color code for a 120/208 system, leading to potential confusion or errors in wiring practices. Understanding these color codes is crucial for compliance with electrical codes and standards, promoting safety and reliability in electrical systems.
