Hi,
just a quick question.
I am replacing a ceiling light and i have 3 sets of wires: 2 sets are red,black,earth but the third is red,red,earth.
I'm happy to connect the first 2 but i'm at a loss with the third.
Your help/advice would be appreciated. |

Hi Hamish,
This should be simple.
It sounds like they have used twin red and earth for the switched live wires, instead of sleeving the black wire on twin core and earth-
Some sparks do use this instead of twin core and earth as it saves sleeving the black wire.
I have attached a picture of what you probably have-

Hi,
Thanks for the reply.
The fitting on the new light has Live/ earth/ neutral so, to be clear, i can treat one of the red on the third cable i mentioned as a black? |

The two red wires from the same cable will be the permanent live going to the switch and the switched live coming back from the switch.
Take a look here-

But instead of having a cable going to the switch with the permanent live in red and switched live in black (sheathed red) you have a permanent live in red and a switched live in red also.
