3 gang switch wiring

[Mwoods4757]

Jo just a quick one! A 3 gang switch for 3 seperate lights.
There doesn't seem to be a feed in from the board or anything just 3 switch wires.
If there was a feed cable I think you would connect live to common link this to all commons and then connect switch lines to l1. Where would the other live cables go in a block? Also if i have no feed coming in can I just put the llive from the switch to c on each switch and switch lines to l1?
Do I still need to link all the commons out?
Thanks in advance.

If there's no live your switch won't work check again you must have a feed there

Are the sw wires twin & earth ?

Are the feeds not from the light ?

 

[ste77]

there must be a feed amongst the three cables

 

[Mwoods4757]

It's all on one circuit. Then each light has a twin and earth going to the switch.

 

[Lighthouse Phil]

are you using T+E or singles ???
If T+E, is one of your cores the phase from the ceiling rose / light ? and the other core the switch line?
or do you only have 3 single core cables at the switch ??

 

[MDJ]

It's all on one circuit. Then each light has a twin and earth going to the switch.

so there is actually 6 cores plus earths at the switch then not 3 cores??????

there must be a feed amongst the three cables

Why?

There could be 3 feeds or switch wires as we call then.

 

[Mwoods4757]

Ah yeah using t and e So one of those is feed. So do I connect one light to each gang in the switch? Do I need to link out the commons some how or just one cable each gang?

 

[brucelee]

so are there 3 Twin and earths in the switch from 3 seperate lights ?? and are are there 3 twins at each of the the ceiling rose/ pendents ie loop in and out apart from if one of them is the last light on the circuit then there will only be 2 twin and earths at the rose
so treat each as seperate 1 gang 1 ways

 

[Mwoods4757]

Yeah one twin all the way round for the circuit from the board looped out at each light. Then one twin from each light to the switch.

 

[tony mc]

Matt I take it that this is your own house ?

 

[ste77]

Why?

There could be 3 feeds or switch wires as we call then.

Im saying there must be a feed at the switch, cant be 3 switch wires

 

[brucelee]

then dont link nothing they are all seperate switch wires and each should be wired seperatley to each gang so they are efectively 1 gang 1 ways but 3 of them in 1 switch

 

[Farmelectrics]

I think a bit of testing is required here soon find what's what

 

[Mwoods4757]

Cool so just live to common and switch to l1 on each switch?

 

[Octopus]

Im saying there must be a feed at the switch, cant be 3 switch wires

Why not?

 

[Lighthouse Phil]

Brucelee has the right answer......and then farmelectrics has too......
He should have called in a sparks

Each switch needs to interrupt the lighting circuit it is controlling. Wiring using T&E it would be just as easy to take a live from each light then loop back to the light again, as it would to link a live feed across the 3 switches.

 

[Johnuk]

get a electrician in

 

[ste77]

Why not?

Has the feed gone on holiday then?

 

[Mwoods4757]

Cool so just the live to common and switch to l1 of each switch from each light?

 

[nikmet]

is it 2 way switching, could be strappers too

 

[Mwoods4757]

I'm trainig to be a sparks. The guy I'm working with isn't very helpful. it's a new wire. We have one t and e from the board all the way round looped at each light and one t and e from each light to the switch. So I think it's just live to common and switch to l1!! That's the way he's wired it.

 

[Johnuk]

well now we know what you are trainee sparks
all he has done
the brown is the live com
and the blue you sleave up and put on l2

i would have wired it differently my self
