Containment spacing regs???

[John Boy]

Hi fella's,

Does anyone know the reg number for containment spacing?

I've just knocked up a shed load of containment giving a 50mm space between the trunking, tray and basket as told to do so. But I was wondering if there is an actual reg number according to bs7671;2018. The only reg I can find in the 18th edition is;

521.10.202; the support of cables in all areas will need to be prevented from premature collapse in the event of fire.

Any help is much appreciated.

Yep, sorry pal....bit vague.

Containment consisting of 225mm and 50mm cable tray, 150mm trunking and 250mm basket for power, lighting, data cable of an office refurb.

Just wondering where to find regs on the spacing between individual types of containment.
