What type of support is required for maintaining conduit stability?

Maintaining conduit stability is essential for ensuring the safety and longevity of electrical systems. The correct response indicates that a combination of fixed and movable supports is necessary.

Fixed supports are crucial because they provide a stable attachment point for the conduit, preventing it from swaying or moving under any stress or external forces. These supports are usually installed at regular intervals to ensure that the entire conduit run is securely held in place, which is vital for preventing sagging and potential damage to the conduit or the components it houses.

Movable supports, on the other hand, allow for some flexibility. They can accommodate thermal expansion and contraction of the conduit material due to temperature changes. This adaptability is critical in environments where temperature fluctuations are common, as it helps to prevent stress on the conduit that could arise from these variations.

A combination of both fixed and movable supports provides a well-rounded approach to maintaining conduit stability, offering the strength needed to resist external forces while also allowing for necessary movement associated with temperature changes. This dual approach ensures that the conduit remains securely positioned while being able to handle dynamic conditions effectively.
