Should cables be placed in corrugated conduit or cable tray
The decision on whether to use a cable tray or a conduit lies on the scale of the job as well as the amount of heat the wires will generate. Cable trays are more preferable in large buildings or factories since they are not closed and can be readily repaired. But how do you decide which one is right for your project? In this post, we'll explore the key differences between cable trays vs conduits, highlight their pros and cons, and guide you toward the best choice based on your application. Conduit systems are enclosed pipes that require precise bends, threading, and pulling. They're excellent for protecting individual circuits in harsh or public areas, but they're labour‑intensive and slower on large cable counts.
