When cables are laid in a common channel, distances must be respected.

 

Separated cable channels

Separated cable channels

 

If the metallic cable channel is divided into different parts, the cables can be laid directly alongside each other. However, one channel must be used per cable category. If only a single cable channel is available, the minimum distances must be respected or metallic partition walls used. These partitions must have a low resistance, low inductance, conductive connection to the cable channel.

 

The metal cable channels should be connected to the building's system of earths and potential equalization. To achieve this, the individual parts of the cable channel should be connected to each other and the building as frequently as possible. Extension grooves and insulated parts must be bridged with earth wires. Earth lines between the separate parts of cable channels must be protected against corrosion.
