Isolator switch wiring help when changing sockets

by LeoLondon » Tue Aug 22, 2023 10:53 am

I’ve been going round my flat changing all the switches and sockets to new flatter ones. I’ve had no problems up till now. The isolator switch I thought might be tricky so I took each wire out one by one and put it into the new one. Or so I thought I had. It didn’t work. So I’ve been looking online for help. I’ve tried different combinations. Nothing has worked.

In the box I have 2 red wires coming up from the light switch. Then I have 2 sets of yellow (brown sleeve), red and blue wires.

I know the blue wires go in the neutral ports. I just can’t figure out where the remaining 6 wires go in the 4 ports that are L1 and L2 (top and bottom). It’s a 3 pole isolator switch from BG.

Any and all help is greatly appreciated.

Thank you

As you are finding, there is no definitive way to connect a light switch / triple pole isolator, and since you do not know, all anyone can do is guess.
A means of safely testing the cables is now your only option. If you can not do this, you are going to need to employ someone who can.

Sorry, it is not the reply you wanted to read. But as I said, there is no definitive colour code for lights/isolators.
