What is the minimum distance that conductors must be supported or clamped near the isolator case?

The minimum distance that conductors must be supported or clamped near the isolator case is established to ensure safety and prevent wear or damage to the conductors due to heat or movement. Conductors should be kept at least 6 inches away from an isolator case, as this distance provides sufficient separation to reduce the risk of overheating or contact with any potentially energized components.

In this context, the isolator case can become quite hot during operation, and adequate spacing helps maintain the integrity of the insulation on the conductors and minimizes any potential hazard associated with proximity to the isolator. Supporting or clamping conductors at this distance is a standard procedure in electrical installations, promoting proper maintenance practices and longevity of the conductors. This guideline ensures compliance with safety codes and best practices in electrical design as per standards such as those put forth by ABYC.
