How should conduits be supported when there is no mechanical damage expected?

Conduits should be supported at intervals to ensure structural integrity, even when there’s no mechanical damage expected. The requirement to support conduits every 10 feet is grounded in safety and code compliance, ensuring that cables and wiring within the conduits are kept secure and protected from strain and potential damage over time. This distance provides a balance between adequate support and practicality, preventing sagging or undue stress on connections and terminations.

Supporting conduits at this interval is typical practice across many electrical codes, reinforcing the importance of maintaining a safe and organized wiring system. The decision to provide support every 10 feet is informed by the need to accommodate potential expansion and contraction of materials, as well as to manage any environmental factors that could affect the conduits. This approach promotes longevity and reliability in the electrical installations.
