Except as provided for in Subrules (2) and (3), metal cable tray shall be bonded at intervals not exceeding 15 m and the size of bonding conductors shall be based on the ampacity of the largest
Step-by-step on-site guide: learn how to plan, mark, support, and install cable trays correctly, from shop drawing approval to final checks.
Cable tray is considered to be a system. It must provide continuous support for cables, and the electrical continuity of the cable tray system must be maintained.
Some applications may require the cable tray to support the weight of a single, dead object in addition to the cable loads. Specifications typically require this to be applied at the midpoint of the span between
