Neutral supported cables should be supported at no more than what length?

Neutral supported cables must be secured at specified intervals to ensure safety and compliance with electrical codes. The correct maximum support length for these cables is 38 meters. This requirement is established to prevent sagging, mechanical stress, and potential damage over longer spans.

Supporting cables at intervals longer than this could lead to issues such as increased strain on the connections and insulation, which could ultimately result in failures or hazards. Thus, the regulation aims to maintain integrity and safety in electrical installations by enforcing strict guidelines on the support distances for neutral supported cables.
