When installing raceway systems, what must not be allowed between conductors?

Inductive heating occurs when alternating current (AC) flowing through conductors produces a magnetic field, which can cause nearby conductors to become energized through electromagnetic induction. This can lead to overheating and potential damage to both the wiring and any connected devices. Proper installation of raceway systems requires that conductors be arranged in a way that minimizes the risk of inductive heating. Controlling the spacing and orientation of the conductors helps to prevent unwanted heating effects caused by magnetic coupling, ensuring the overall safety and efficiency of the electrical system.

Maintaining proper physical separation between conductors can help mitigate the risks associated with inductive heating, thus making it critical to manage this phenomenon when designing and installing raceway systems.
