Are the cable tray expansion joints and the cable tray clearances the same
The spacing between expansion joints varies and is determined by the type of metals and the extent to which there is a change in temperature. A typical joint spacing of an aluminum system is 65 feet for a typical temperature change of 100°F. The metal gets longer, and the heat becomes excessive. In case there is no space to move it, the tray could become deformed or break the bolts that attach. NEC Article 392 outlines the key rules for installing and maintaining industrial cable tray systems. These systems, made from metal or plastic, are open structures designed to support electrical conductors, ensuring proper organization and safety.
