When multiple conductors of the same insulation color go through conduit, what is necessary?

Identifying each phase cable prior to installation is crucial when multiple conductors of the same insulation color run through conduit. This is important for several reasons. First, it helps ensure safety by preventing confusion during installation, maintenance, or troubleshooting, where misidentifying cables could lead to incorrect connections or live voltage exposure.

Furthermore, clear identification aids in compliance with electrical codes and standards, which often require that conductors be easily distinguishable to facilitate safe operations and maintenance procedures. Proper identification of conductors also supports accurate electrical and load balancing, ensuring reliability in the system's performance.

In scenarios where the same color insulation is used, failing to identify each phase cable could lead to operational issues, increased downtime, and the risk of accidents—all of which can be avoided through proper labeling and identification ahead of installation.
