Lighting question

Former Community Member over 5 years ago

So today I wanted to add another switch in a house.

The extra switch would need to now include an intermediate due to it being already 2wY.

now when I took the switches off, one switch the common has just a single sheath core, the L1 and L2 are a 2 core cable L1 being Red and L2 being black.

This is exactly the same in the other switch.

I thought this must mean there is a JB somewhere ? In the light fitting there is 3 T&E, and 1 single cable which goes into the lamp live!

I just can’t understand how this could be wired?

Any ideas?

I am not clear how this makes a circuit.

The two core cable comprises the strappers. One end of the single core goes to L on the load and then to switch one. The other single core goes from switch two to the supply - where is that? Obviously, there is a N to the load, but I am not sure what the "3 T&E" does - presumably it carries N, but what else?

If you want to put in an intermediate switch, you have to put it in the two core cable somewhere.

There is no mention of a CPC. Is there one?
