What may happen if conductors are not spaced correctly in vertical runs?

When conductors are not spaced correctly in vertical runs, overheating may occur due to a variety of factors. Proper spacing is crucial for allowing adequate airflow around the conductors, which helps dissipate heat generated during electrical current flow.

If conductors are too close together, their heat can accumulate, leading to higher temperatures than what the insulation materials are rated for. This overheating can degrade insulation over time, increase resistance, and even lead to short circuits or electrical fires.

Thus, ensuring proper spacing in conductor installations is critical for maintaining safe operating temperatures and overall system efficiency. Proper management of heat and airflow contributes to both the longevity of the wiring system and the safety of the electrical installation.
