Got a job where a sparks is suggesting omitting mains cable tray and runnign armoured cables in a run of cold rolled steel channel.
Steelwork seems to have nowhere to properly fasten cables whether cleats for bigger (70-95mm size) or tie wraps for smaller. Unless they want to wrap something around the whole thing?
Also some small screw ends popping which they are saying can be blunted.
The steel is only about a hundred wide and has some vertical struts going up from the middle so not really much useful space.
Surely there is a Reg that says you need to fasten cables properly even if they are laying inside a channel or tray? I just want to say no, put some containment in, but trying to find a reg that will put a stop to it.
Any thoughts on that?
