Where power-limited conductors are installed in the same enclosures as power and lighting conductors, they must have a separation of at least what measurement?

When power-limited conductors are installed alongside power and lighting conductors within the same enclosure, it is essential to maintain a specified separation to ensure safety and performance. The requirement for a minimum separation distance of 1/4” helps to prevent electromagnetic interference and minimizes the risk of voltage potential differences between the various types of conductors.

This separation is critical because power conductors carry substantially higher voltages and might induce electrical noise or create voltage fluctuations that could affect the sensitive signals carried by power-limited conductors. By adhering to this separation, installations can maintain the integrity of both power-limited and power conductors, protecting sensitive equipment and ensuring compliance with safety codes. The other distances provided do not meet regulatory requirements, making 1/4” the standard necessary for safe and effective installation.
