Cable ladders and cable trays should be mounted far enough off the floor or roof to allow the cables to exit through the bottom of the cable ladder or cable tray.
Core Principles for Electrical and Instrumentation Cable
Straightforward Pathways: Cable trays should follow the shortest practical route between equipment, minimizing the need for unnecessary bends and junctions.
Cable Support Distances
This provides distances for cables based on their diameter and cable type. Prysmian was instrumental in providing this information and an extract is provided in this document.
Cable Tray Width Selection for Installations with 600 Volt Single
Space between cables must be equal to one cable diameter -- 11 x 1.07 inches = 11.77 inches. Total cable tray width required is 12.84 inches + 11.77 inches = 24.61 inches.
