What does Section 250.24(C) require for the grounded (neutral) conductor?

Section 250.24(C) addresses the requirements for the grounded (neutral) conductor and emphasizes that it must be routed with the phase conductors in the same raceway or cable assembly. This is crucial for maintaining the integrity of the electrical system and ensuring that the neutral conductor has the same potential as the phase conductors it serves. Routing the neutral with the phases helps to ensure that all conductors are properly managed together, reducing the risk of electromagnetic interference and ensuring safer electrical installations.

In practice, when the grounded conductor is run alongside the phase conductors, it allows for a balanced electrical load and helps prevent potential issues that could arise from having conductors separated. This conjunction also aids in proper circuit functioning, as it allows return current to flow effectively through the neutral, assuming a balanced load scenario.

While the possibilities of routing the neutral in a separate raceway or requiring it to be grounded at all times are important considerations in electrical safety and design, they do not specifically reflect the requirement stipulated in Section 250.24(C). The coloring of the neutral conductor, typically white, is significant for identification but not the core focus of what this section mandates regarding routing.
