tray separation or not ???????

[multimick]

i have installed some 4inch tray horizontal around a mains room in factory carrying for the moment a couple of 4mm twin earths ,more will be added later, the cctv and data guys have come along and tywrapped their cat 5 cables to this tray ,it maybe just a temp measure as it is very roughly done at this time ,whats your thoughts on this please .

short avouple of the daya cables out at one end. then stick a car battery across the other end.

put a claymore inside their toolbox and hook the trigger up to the lid of the box, then sit back

get the big drill out and put it right through the bottom of their toolbox with a 20mm masonry bit into the ground, pop a few 20mm anchors into the holes and fix to the ground

get the grinder out and make them a sunroof for their van

the list is endless

no it isnt, if youve quoted for supporting cables on 4" tray then that tray is ALL yours once you install it

data guy wants ready fitted 4" tray he can fit it himself or see me outside for a fight

Jolly good,this will be welcome news,to the various nations battling over the mineral rights,under the Arctic ocean...

do they need me to mediate a solution for them?

Departures from BS7671 must afford at least the same degree of safety as compliance. It's not there as a means of not complying with the Standard when it suits.

Absolutely correct. There is zero safety reasons to not run telephone cables om the same tray as LV cables in this scenario. Hence the departure.

Its probably because the Data Guys cant do containment work and have robbed your nice tray work to pin there cables to.

Did they strap it in the tray, or on the side, if it is not in your way then it is not your problem, if it is, and you need the full tray then I would make that clear to the data guys. The lack of separation / segregation is not your responsibility, unless it was in your spec to provide containment for data cables, in my opinion.

its in a mains room whats wrong with that .i have also used it in offices whats wrong with that as well

Is the insulation of the t+e suitable for the environment in which it is used, I'm not saying it isn't, but that is a big factor of cable selection to me, I would used, armoured SWA, conduit, or sy-flex normally.

Tell the boogers to fit their own containment an don't use yours, not going to happen of course, but you asked the question.
