5. Using cable trays instead of conduit: A look at the advantages

In plant retrofit and expansion projects, it’s not just a matter of saving on capital equipment and labor costs, but also getting the job done quicker so the plant can get back to full productivity.

In many installations, one way to achieve these goals is to use armored, metal-clad and other permitted cable types installed in cable trays wherever practical. While the initial cost of the cable may be higher than non-armored cables protected by conduit, the labor time and cost of a cable tray installation can be much lower. That’s because working with conduit and pulling wires is extremely labor-intensive. And in hazardous locations, there’s also the work of installing and inspecting sealing fittings.
