When conductors are run in separate cables or raceways in parallel, what is required regarding the number of conductors?

When conductors are run in separate cables or raceways in parallel, it is required that they must have the same number of conductors. This requirement helps to ensure balanced loading across the conductors, maintaining equal current distribution and reducing the potential for overheating. Having the same number of conductors in parallel is crucial for proper operation, as differences in the number of conductors can lead to imbalances, affecting performance and safety.

In electrical systems, when parallel conductors are employed, each conductor should carry its share of the load. If the conductors do not have the same count, this could result in one conductor being overloaded while others remain under-loaded, particularly in circuits with varying loads or in fault conditions. Thus, adhering strictly to the same number of conductors is vital for both efficiency and safety in electrical installations.
