    Hope someone can help? I am putting a new pendant light fitting up but when I put the wires in the same order as the previous one the mcb trips. 3 cables for lighting but only 2 have red, black and earth - other has just black. There is no red sleeve on the other black but it was in the live block in the previous pendant so assumed it was the switch live.

    Any help appreciated

    Post a picture of how the wiring was originally (if you can) and one of how you have it now.
