Hi all,

New to the forum, question regarding Band 1 and Band 2 segregation...

So on a site I'm working on, installing access control system. Now the access control panels have designated metal trunking for all relevant cables being low voltage. The trunking is directly above the panels. The fused spurs powering said panels are then coming out the top of the same trunking.

Would it be allowed for the fused supply out the spur to the panel, to run through the metal trunking inside kopex, so not to effect the low voltage access control cabling. I was thinking running kopex inside where they mix with the other cables, to conform with segregating band 1 and band 2 type cables . The singles will be removed as they are supplied by a 3rd party who have just run them in the trunking.

Got a pic for reference:

could you not just drop the enclosure below the trunking and put the fused spur there. wouldn't need too much space. it saves running it down through the trunking.

Unfortunately they have benchmarked this set up, and was approved by the architect, so the layout has to remain

By Low Voltage what do you mean? mains wiring is Low Voltage.

As long as the voltage rating for the ELV cabling is rated at or above the highest voltage present, segregation would be achieved.

Yes. I have run power through kopex inside data trunking as I believe it keeps it segregated.

Yes, I've used kopex inside trunking and on tray/basket for the same reason. This is not the ideal solution, but sometimes you just have to work with what you've got.
