Help! Kitchen circuit not working and earth wire showing as live...

[Warehouse_kres]

Hi I removed a light in the utility room which has a lot of wires and the reds were connected in a nylon block, all others connected to the light but unfortunately I didn't take a picture and cannot remember which wires went where...

I have tried connecting all 3 black wires in a wago along with the blue and brown in a separate wago but this hasn't helped also two of the earth cables are showing as live when tested with a screwdriver which illuminates but I have absolutely no idea why?

Any help would be great, have attached a picture showing the cabling

First step is to loosen the switch screws and see what colour wires are in the back

Did any of the blacks have a red marker sleeve?

Some more pictures showing wires separated out

Does the far left cable have two brown insulated conductors ,one blue, and no bare copper earth conductor ??

 

[Warehouse_kres]

Terryplumb yes no earth in that far left cable

Sunray none of them had any colour sleeving

Andyprk the switch had one red, one black and one earth cable

The room used to be a bathroom so the switch was a pullcoard

Have you got enough terminal blocks ,or connector blocks to do this....
Put all three reds into one connector block.
Put all three earth conductors together in a second terminal block.
Put the three blacks in 3 seperate terminal blocks ,so they are not touching each other in any way.
The cable that has two brown and one blue, put each one of them into seperate connector blocks ,so they are not in contact with each other.
So you need 8 seperate terminal blocks.

Yes I should be able to do this, before I do can I ask what your thinking is ? Will it complete the circuit and stop the earth becoming live?

 

[terryplumb]

Neon screwdrivers are next to useless ,you can probably make yours light up if you run it on your sleeve.
By the way have you blown any fuses or tripped any breakers whilst working on these wires ?
You obviously need to turn mains power off to do as I told you .

 

[Warehouse_kres]

No fuses have been blown but the RCD doesn't have RCBO for the lights. Yes of course mains will be off when working on any electrics

 

[terryplumb]

What I have told you to do is only the first step to firstly terminate the conductors ,seperate them ,and next will be to identify which are neutrals and which is switched live.

Okay thanks very much I'm going to have a go at this tomorrow in daylight, don't fancy risking anything tonight in the dark... Will let you know how I get on tomorrow

Hi Terry I have done what you asked and now the black wire on the far right is showing as live along with the 3 red wires

 

[sparkwright]

Before Terry comes along to tell you what to do next, what is that cable with the browns and blue?

It appears to consist of two brown wires, one blue, and no earth.

Have I got that right?

 

[terryplumb]

If you operate the switch , is that black wire live when switch is in "on" position ,and not live when switch is in " off" position ? So turning the switch on and off ,that black wire would be live/not live . If so that is the switched live .
