Suspended ceiling - how do you run lighting calbles ? ? ?

[grandad]

yes there is 18 ( 3 x 6 ) luminaiers and the area is more less 8 x 14



perfect - and this is the stuff that i am gonna use for this job, just wonder how strong is the fixing and if will handle a bunch of for example 5 x 2.5mm2 but that is not the problem as they do not need to be bunched in 5

they are really strong ,once in you cant get em out....all depends on the size of tie wrap as to how many cables

 

[joe kane]

U should keep cables off a ceiling grid as it isnt earthed it could become live in the event of a fault.The cheapest and easiest way is to use metal allround band and make a loop and drill and screw it to the concrete ceiling above the suspended%2

 

[dkent5]

Hager Klik are always the best option as when you've installed your lighting as per the plan some plank will come along and put lockers/MCC panels or anything else that will block the light directly underneath and you'll have to move everything.

 

[benji]

Why arn't you earthing the ceiling grid
yours benji

 

[dkent5]

What would you call it Benji? Extraneous or supplementary?

 

[Spudnik]

i think one of the main reasons for keeping cables off the grid is because of the weight of them.

 

[joe kane]

There was an occasion in belfast where a fault developed on a ceiling grid with cables the ceiling fitter stuck to it.Nothing to do with weight.How can u earth a ceiling gid they are clipped together and give poor continuity.

READ MY POST.

I said ONE of the reasons.

Wire it up in Conduit,Wire armour,Trunking whatever to one of these or simmilar

Kilk - Lighting Distribution System Hager


Then flex drops to the fittings.

Hi Scott, ive not seen one of these Klik sytems before, I cant see forom the website the length of the prewired connections, as youve used these any info please

 

[scotsparky]

Trebor the prewired connection come in a veriety of lenghts but a coil of flex and the connections and you can make them whatever lenght you need. When i served my time in first year it was an apprentices job to sit and make them up.

 

[joe kane]

good job scotty but looks expensive.

 

[dkent5]

Trebor go onto Schneider Electric - Electrical Distribution and Automation and Control , I think thats the website but you can google schneider if you like. I normally buy the bare units and put my own flex on.

 

[adamh]

like some1 else said the easiest way is these black plug things (forgot there name) but you just drill a hole knock it in with a hammer and there is an eye for a cable tie to go through electricfix catalogue page 55

 

[Spudnik]

So how would we go about fixing to a fire resistant plasterboard ceiling above a suspended ceiling in a shop with flats above?

gripfill? lol

Use angle bracket screwed through the plasterboard into the joists

 

[Spudnik]

Use angle bracket screwed through the plasterboard into the joists

Not splitting hairs but i thought we were not allowed to penetrate the fire barrier?

 

[sparks1234]

Ah, how do they screw the plasterboards up then.....go on....

 

[Guest123]

They dont, they use sellotape.

 

[Spudnik]

With those special fire resistant screws dont ya know.

Ok ill get me coat
