Fitting a bathroom light

[SteveWyres]

Hello

I have just tried to fit a bathroom light. I have removed the old one which was a rose type but the new light only has neutral and live wires.

I have plugged the mains into the pull cord switch and then added a wire to the light.

Problem being when i pull the cord the fuse trips.

On the pull cord there is an earth, C, L1 and L2. I have plugged the mains earth into the earth, Neutral into C, and the live into L1. With the wire to the light, the Neutral goes into C and the live into L2.

Anybody any ideas?

Thanks

Yes - what you've done is completely wrong.

You did not need to "add a wire to the light". There is no neutral at a switch - the cable going to it has the live feed on the red conductor and the black one is used for the switched live. OOI - why did you think the light was working OK before without this cable, if you thought you needed to add it?

The MCB is tripping because, pound to a penny, you connected all the reds together and all the blacks together at the light, didn't you. One of those blacks is the switched live from the switch, so when you turn the switch on you are creating a live/neutral short circuit.

You need to look at the diagrams in the reference section to see how lighting circuits work.

Then you need to undo the connections you've made, remove the new cable you added, and work out which wires are which. If you didn't label them and make notes of which went where in the old ceiling rose, or if you don't have a multimeter, that may not be easy.

How many cables were there at the rose?
