Installation instructions of metal wire trunking
Cable management system designs should comply with national standards. It is recommended that installation work is performed by qualified personnel, preferably a certified electrical contractor familiar with standard electrical construction practices, electrical equipment, and the safety of electrical wiring systems.
·Support Span
The strength of a cable tray system is largely determined by the strength of its side rails. The strength of a cable tray side rail is reversely proportionate to the distance between the supports on which it is installed, commonly referred to as the “support span”. Therefore, the strength of a cable tray system can be altered by changing the support span. However, there is a limit to how much that strength can be increased by reducing the support span. Once the load requirement has been determined, the following
factors should be considered:
(1) Sometimes the location of existing structural beams will dictate the cable tray support span. This is typical with outdoor installations where adding intermediate supports could be financially prohibitive. For this situation the appropriate cable tray must be selected to accommodate the existing span.
(2) When cable tray supports are randomly located, the added cost of a higher strength cable tray system should be compared to the cost of additional supports.
(3) The support span lengths should be equal to or less than unspliced straight section lengths, to ensure that no more than one splice is placed between supports.
·Support Installation
Supports for cable trays should provide strength and working load capabilities sufficient to meet the load requirement of the cable tray wiring system. Consideration should be given to the loads associated with future cable additions or any other additional loads applied to the cable tray system or the cable tray support system.
