How long should a cable tray be before adding an expansion joint
For a 100° F differential (winter to summer), a steel cable tray will require an expansion joint every 128 feet and an aluminum cable tray every 65 feet. The temperature at the time of installation will dictate the gap setting. Cable tray systems, essential for supporting electrical cables, are subject to thermal expansion and contraction due to temperature fluctuations. The metal shrinks and shortens when it becomes cold. In case there is no space to move it, the tray could become deformed or break the bolts that attach. Alls I have found is 392.
