Cabling within closets

Cabling within closets
When running cables within cubicles and cabinets, remember the following rules:
● Install the cables in metallic, electrically conductive cable channels.
● Screw the cable channels to the struts of the rack or cubicle walls approximately every 50
● Separate the cables according to the categories as shown in table 1-1.
● Maintain the minimum clearance between the cables of different categories as explained
● Where cables of different categories cross, they should cross approximately at right
● The shields of all cables entering the wiring closet should make largearea contact with

Cabling within buildings

Cabling within buildings
When laying cables outside cabinets but within buildings, note the following points:
● Install the cables in metallic, electrically conductive cable channels.
● Include the metal cable channels and racks in the bonding system of the building or plant.
● Separate the cables according to the categories as described in table 11 and run the
