3phase industrial - clear a couple of things up?

[apprent10]

I know, its going to look shocking! Im glad its not my name going on any paperwork!!

So to answer my original question, is it against any regs to do it this way??

thanks.

Well I'm sure if you paw through selection and erection, protection of cables, etc etc etc you will come to the conclusion ( the picture im painting of it anyway) is yes.)
You never know his term chuck em over the ceiling might mean cable tied to 50mm suspended tray

Hi guys.

Well i decided to ask him today, as im always told that asking questions is a good thing!(?)

He made it very clear that just laying the cables on the grid is the idea, and that is the way it can be done. I asked what about the regs on containing them and he said theres no problem here.

I havn't got any books as yet, but i will be asking at college on friday.

Regards.

there's no problem as far as that's concerned. it's not pretty, but it's not wrong

the cable is adequately supported (by the false ceiling) and the unfortunate part of it is, they can throw JB's wherever they like as it's considered accessible for inspection and maintenance

J.Bs what are they?

 

[baldsparkies]

Just take a peek above the suspended ceilings in many shops and offices, twin and earths sprawled everywhere in many cases.Its not nice and not ideal but then,welcome to the real world.

J.Bs = Joint boxes.

Ok thanks for the other replys, i know many many others do it, so you think its all ok to do it like that, so long as the cables are protected from any sharpe edges there may be.


cheers

The last op that used a srew terminal JB on a job of mine got his **** kicked for 5 mins , sat on the naughty step for a week on breaks and had to tear the pages out of his pocket mk catalouge!

I only use JBs on a very last resort, if the cable cant be pulled back and replaced etc.

As for 'appret10' hi-jacking my thread ( lol)...You do see almost every place with false grid ceilings with justr cables thrown above them, i dont 'think' its against any rules as long as they are protected from sharpes etc.
Somebody correct me if im wrong though!

Though i would try my best to support them the best you can, like clip them up just off the grid, on the suspended wires? Or even clip along the perimeter walls where you can??

Mark.

There you go then , when you've popped a few ceiling tiles and a ton of cables come down on top you
you'll get the gist of what Im saying

 

[apprent10]

Sorry screech lol. Thanks for the reply tho

Bigsy... no sorry I don't get your gist...


Thanks

Its Just looks rough as a badgers ****.

You would think he would at least have used a spot of round band and took the weight off the ceiling / tidy it up a bit

You cannot run cables across the ceiling grids they must be adequately supported and not by laying them on the grid, ive only come across one type of cable allowed before which had been designed to withstand the sharp edges of the grid frame.

Reg 522.6.5, Reg 522.8.1 to name a few would give the impression that laying cables on grid ceilings isn't acceptable as the junction points of the grid are very sharp and can lead to damage of the cable during installation or maintenance whether it be you or another trade gaining access, a nicked cable could make the whole grid live!!! as earthing the grid isn't required and any light fittings have usually got an insulation layer of paint between their earth and the grid.
Its clear your on your learning curve and open to suggestion by your company but it beggars belief they are employing this practice or intend to, unfortunately it puts you in an awkward position.
