Ceiling wiring help needed with what wires go where Ask questions and find answers to many subjects relating to electrics and electrical work

[Boz]

Hi.
I have 2 red (L) , 2 black (N) and 1 earth wire in ceiling.
I have 3 blocks in light fitting.
What goes where?
I have tried both Red into one block, both black into one block and earth into other
But this trips out.
Can you help?
Thanks.

Lucky you only have two cables, usually it is three.
First, you need to find the 2nd earth wire. It may be you think you have just one, but you may have two, twisted together in the same sleeving?

You also need ANOTHER connector, wagos are best.

I do not know how your light fitting is exactly configured (You do not say.) But for the sake of argument I am going to assume that the light connector block is connected as:

Live - Earth - Neutral

You connect your cables:
(One) Black to Live
(Your earths) to Earth
(One) Black to Neutral

The TWO reds go into the extra connector (or wago) I mentioned earlier. (They do not connect to anything else)

You obviously turn the electricity off and on as required.

For future reference get a good multi meter and learn how to use it.
Always mark your cable cores and TAKE several pictures BEFORE you do anything else.
