I'm changing a light fixture in my kitchen. It's something I've done plenty of times but this one keeps on tripping my circuit breaker fuse, cutting power to all my downstairs lights.
The only difference I can see with this setup to all the others I've done myself is the light itself has an earth wire whereas all the other lights only have live and neutral.
My ceiling rose is a loop circuit which has 3 of each coloured cable. Brown for live, Blue for neutral and Green & Yellow striped for earth.
The light itself is a 5 arm ceiling light. It has one brown wire, one blue wire and one green/yellow wire. It then has a second green/yellow wire connected to dome that hides the wires in the ceiling (because its metal).
So I'm connecting blue to blue, brown to brown and both green/yellow all to to the right place but it just trips the fuse as soon as I turn the electric back on (even if the light switch is off).
I've tested the light by wiring it up to a plug and running it from a wall socket and it works fine! And when the light isn't in the ceiling, the fuse doesn't trip.
What am I doing wrong? Should I be doing something else with this earth wire? I've never seen a light with an earth wire before (except for the ground wire connected to metal fixtures)
Edit: I think I may have found a problem! I was taking some photos for you and it looks like one of the live wires is melted. I'll attach the photos for you. Please note I did not install the ceiling roses. They were there when I moved in. I just put my light fittings on them. They look quite old and it may be hard for you to see because it seems quite "cramped" in there.
If the live wire is indeed melted does this mean the light is too powerful and has overloaded it? I'm guessing this is going to need to be replaced now?
