What are the requirements for cable segregation? The factory I’m carrying out work in just now has Ladder rack containing SWA and cat 6 data cables which are lying on top. Also another cable tray which has Fp-200 fire alarm cable and SWA on it.

lastly should all the above now be supported with metal tie wraps?
Thanks
 
1. depends on the voltage rating of the cat6.
2. Fire alarm cables should be segregated from all other circuits.
3. I don't consider metal cable fixings required on a vertical cable run, but a RA should be carried out.
all IMO.
 
If the mains cables are all SWA then no problem for the CAT6 cables as they have an earthed screen between the high and low voltage anyway.

I thought similar, with regards to cable fixings I’m probs overthinking it but I’ll probs install a metal tie wrap every 2 metres to keep myself right

521.10.202 Wiring systems shall be supported such that they will not be liable to premature collapse in the event of a fire.
NOTE 1: Wiring systems hanging across access or egress routes may hinder evacuation and firefighting activities.
NOTE 2: Cables installed in or on steel cable containment systems are deemed to meet the requirements of this regulation.
NOTE 3: This regulation precludes, for example, the use of non-metallic cable clips or cable ties as the sole means of support where cables are clipped direct to exposed surfaces or suspended under cable tray, and the use of non-metallic cable trunking as the sole means of support of the cables therein.
NOTE 4: Suitably spaced steel or copper clips, saddles or ties are examples that will meet the requirements of this regulation.
