Cable tray section numbers are used to specify the type, dimensions, and material of a cable tray section. These numbers help engineers, installers, and suppliers ensure the correct tray is selected for a project. A typical cable tray system includes straight sections, bends, tees, elbows, drop-outs, supports, and accessories, each of which may have a unique section number for identification and ordering purposes .
A cable tray section number often encodes the following information:
Cable tray section numbers are often aligned with NEMA VE 1 standards, which define metallic cable tray systems, including dimensions, load ratings, and testing procedures . Compliance with these standards ensures that the tray can safely support electrical cables without sagging or damage. Manufacturers may also follow ANSI, ASTM, or UL specifications for materials and coatings .
