What is a major advantage of wire mesh cable tray (WMCT) installations?

The major advantage of wire mesh cable tray (WMCT) installations lies in their flexibility and ease of installation, particularly in the ability to field modify and bend the cable tray on-site. This feature allows electricians to adapt the cable tray to suit various configurations and pathway requirements without the need for extensive pre-manufactured components. As installations often require some degree of customization to navigate existing structures, obstructions, or to fit specific project designs, WMCT proves to be a practical choice.

This capability of bending and modifying WMCT on-site enhances efficiency during installation since workers can make adjustments as needed without having to wait for additional materials to be delivered or manufactured. This adaptability makes WMCT particularly valuable in dynamic installation environments where routing may change as the project evolves.

Other options, while they may contain some level of truth, do not capture the primary benefit of WMCT to the same extent. For instance, while WMCT can potentially use fewer supports or hangers and may support large electrical cables, those characteristics do not represent the key advantage of flexibility and onsite adaptability in installation practices. Additionally, grounding requirements can still apply, depending on codes and local regulations. Hence, the ability to modify and bend the tray on-site stands out as the most significant feature.
