The document outlines the specifications for the supply, fabrication, and installation of various types of cable trays and raceways made from hot-dipped galvanized steel.
A generic guideline developed by the Cable Tray Institute indicates that cable trays should not be filled in excess of 40-50% of the inside area of the tray or of the tray''s maximum weight based on the cable
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
This guide for engineers and installers has been developed by ABB as a practical reference regarding cable tray characteristics, installation, and requirements.
The Cable Tray Institute is making available the current edition of this practical guide for the proper installation of aluminum or steel cable tray systems. These guidelines will be useful to engineers,
If it has excellent electrical continuity and is integrated in the installation''s equipotential bonding system, a metal cable tray reduces the coupling''s impact and thus contributes to good EMC of the electrical
The work covered under this section consists of the furnishing of all necessary labor, supervision, materials, equipment, tests and services to install complete cable tray systems as shown on the
