Spacing of horizontal supports for metal cable trays
For horizontal sections where cable trays are laid out in a straight line, the typical support span (distance between supports) should range from 1. This range allows for easy access and efficient maintenance. The spacing between trays, whether horizontal or vertical, depends on various factors like cable type, environment, and tray material. Proper installation can significantly reduce electromagnetic interference, prevent fire hazards, and improve overall efficiency. The National Electrical Code is a set of principles designed to promote public safety and welfare, as well as safeguard public health by regulating the design and operation of electrical facilities and. Although BS 7671 touches on the subject of cable supports, it does not detail specifically what these support distances should be. Clause 522-08-04 Where conductors or cables are not supported. NEC Article 392 outlines the key rules for installing and maintaining industrial cable tray systems.
