One to confuse you all!!

[axel132132]

Right then this has now happened to me twice.. and ive not a clue whats going on so if anyone has had the same issue it would be good to see what causing it.

Anyways SO i have a 2G2W light switch upstairs and a 2G2W light switch downstairs.. I Wire them both correct.. Up have Brown from 3-core in Common, then black in L1 and grey in L2 and Live in in L1 and Live out in L2.. that controls the lights on the stairs..

Then i do exactly the same with the upstairs lights. Feed in, feed out L1 + L2 etc.. ok all simple so far..

NOW COMES THE CONFUSING BIT..

The stair lights are working fine on the 2-way wikid..
The LED spotlights in the celing dont work.. OK

SO i swap the cables, basically swapping the switch.. NOW the LED spotlights work on the 2-way but the stair lights dont..

OK so maybe the switch is broke.. Change the switch (TWICE still dosent work)..

Umm maybe i have a strapper down or something.. Bell out the strappers.. BELL OUT FINE.. ok now WHAT the hell is going on here??????? Switch is fine, strappers fine and if i move the strappers from one switch to the other it works so this proves that the Live IN to switch and the Live to the light works an that all the lamps are working..

any ideas anyone?

cheers

Where are you taking the "feeds" from?

 

[MDJ]

Murdoch it sounds like the feed and switch wire are dropped from the lights via a T&E and then a 3 core between switches, so 5 cores at the switch one end and 3 at the other, may be a strapper on the wrong switch.

Yeh the feeds are to the switch so in switch have Feed in, Feed out, and then Switch out so 3 Lives and the Neutrals are connected in a Wago connector in the back.

Silly question but didn't this issue show up when you were testing your R1+R2?

 

[VoltzElectrical]

you did link the commons out to provide power to both switches in the 2 gang didn't you?

 

[axel132132]

Yeh i did indeed its SO MENTAL ive no idea.. Not tested yet its new build 2nd fix

Now you've confused me.

The lights don't work with the power on, its a new build, not tested yet?

 

[VoltzElectrical]

so at the upstairs switch you have 2 x 3-core cables?

 

[ackbarthestar]

I think all will become obvious when you sit down and draw a wiring diagram of what you would expect to happen and then compare it with what you have actually got.
I can't help thinking that it something very simple such as as voltz has described

 

[VoltzElectrical]

take the live in, out of the switch, and put it in a wago. Add both switch wires. Lights should be permanently on. This will confirm the switch wires. Then you have a feed problem somewhere. Double check the linked commons in the switch, it can't be anything else.


And do let us know!

Yeh 2 x 3 cores.. we have had 3 electricians look at it now.. AND ITS A MISTERY!! No one understands why its not working.. the 2 way next to it is WIRED EXACTLY THE SAME ackbar.. and that works fine so its not the wiring thats wrong lol.. and yeh murdoch, i 2nd fixing everything.. everything second fixed power on to make sure lightings goes on.. umm 2way does nothing.. wont switch the light on or anything absolutely MENTAL

 

[axel132132]

Yeh i did that voltz linked it all through and lights were on.. It is the worlds most craziest issue i think theres something paranormal about this switch ..?!

Sorry mate but I'm not sure that switching on the power before you've done the requisit dead tests is the right thing to do.

Nope prob not but i did it anyway =]
