Office wiring cabling

[mattyhop]

Hi guys,

Just a quick bit of info if you could, I am currently working on a office building with a raised floor (the type with metal and wood tiles) I have got to install floor boxes in various positions and am intending to use T&E.

Do I need to have additional mechanical protection on these cables or is it ok to starp them to the concete floor below?

Thanks

on our site the floor boxes come off a 63a busbar.each box is fed from the track in a metallic kopex from track to box,so i would say yes.

Not saying its right but i dont see why you need to run it in anything at all.

Not really much different from running them under a 'normal' floor.

I would at least run some basket or tray under rather than straight on the concreate?

I know of this but there just isnt the costs in for this, you know how it is.

I just want to make sure the regs say its ok to do so.

Thanks

Use tray !

It'll look a bag of ****e T/E left loose under the floor (if I remember I'll take a pick of a place thats due a rewire just like this), then the alarm bt & cctv boys will come in & drape their cables across your LV cables, because the always take the shortest route & never use the tray you put in.
