'Click' lighting outlets and cable lengths.

[SMB]

More questions....yawn.

I am required to wire a couble of flu's into a small extention within a building.

I have removed the lights which were at high level before the extention was built.

These lights were connected to a 'click' outlet.

I was hoping to re-use this 'click' outlet to feed the lights in the new extention. The outlet is connected to a metal conduit through box. The drop from this through box to the new lights is about 3 meters.

In a perfect world then conduit from this through box down to the new lighting height would be ideal, but im not sure how to do that....a 'spout' conduit outlet has been suggested to drop the wiring into the new extention. That seems like alot of hassle. There are no risks of this cable being damaged, it is out sight and there is no risk to the cable from damage etc as far as I can see.

Does anyone know what the maximum length that flex can be used from a 'click' lighting outlet? And where does this say so in the BRB?

With the drop of 3 meters and the loop between the flu's I recon the whole flex installation will measure 5 meters in length.

Thanks in advance (I promise this will be my last question of the day......there will be more tommorow unfortunately......laugh / panic).

It's 3m as per 434.2.1, although I've seen klik flexes longer than that and wouldn't lose musch sleep over a slight deviation from that.
What do you mean by a 'spout' conduit outlet? Is that where you would screw a stop end box with a hole in the back over the top of the through box and tube down from that?

Ahhh....yes....perhaps that is what the person ment, and that would make things okay. Attach a stop end box to the exsisting through box, bend the conduit at ninety degrees and drop down to the boarded roof of the extention. Attach another stop-end box and 'klik' from there to the lights?

I was imagining a 'spout' outlet to be like a lid to the exsisting through box but with a threaded 'spout' in the middle.

God I must sound like a fool.

I can wire houses with me eyes shut, but this is a totally different ball game that I have just entered. I like it, but only if I know what im doing. If im confused by what im doing then I panic.

Thanks again Novus, thats helped, I can do that.

If ive got the above wrong then let me know, or if there is a better way please inform me.

I really have appriciated your help today.

All the best.

Mate I'm probably the other way round - I'm fine with commercial type systems but when it comes to domestic I seem to spend hours overcomplicating simple issues.

Yeah that's basically it, although you can probably just turn the end box around and drill some extra holes in the back in the right place so it's already pointing in the right direction and you can just set back towards the wall, then like you say straight down and another box on the end for the rose. You might even be able to do it in plastic if that wouldn't look out of place.

Ta Novus......I just laughed at myself about the ninety degree comment whilst staring at the stars in my garden.....ofcourse I will be able to turn the stop-end box to point downwards, another straight forward straight drop. No plastic allowed where I am, metal all the way.

I feel so much happier about the job now, its not rocket science, its not worth getting stressed about. I am able to do it.

Thankyou.

Its bed time......


Bloody pyro will be my next headache........grin.

Its all a learning curve.

Kliks must be accesable , is it a borded or drop in ceiling

 

[SMB]

Cheers Bugsy, everything will be accessible.

I've just done a PIR where the ceiling was boarded -- pic's yet to be posted

Its a small extention within a huge building.

The roof height of the extention / room is 3 meters below the roof of the main building (where the existing conduit runs).

The conduit drop will go down to the chip-boarded 'roof' of the new extention / room.

Then from there will be 1 klick feeding 2 lights, the cable feeding those lights will then have to be drilled through the chip-boarded 'roof', through the 'floor-space' and though the plaster-board and into the light fittings.

Now im feeling more confident I think I will run the cables from the klick in metal conduit accross the chip-boarded 'roof' to the lighting points.

The job is sorted in my head now.

Im hoping not to dream about it...........snore.
