    Hi guys would appreciate a bit of advice as to how to wire a new light. As you can see in the pictures the new light only has three terminals, so would like your help with which wires to put where, I know the photo isn't great but would appreciate any help thanks in advance

    Excuse TTC's rudeness, we are not all like that. (Thinking about it, has anyone seen BAS recently, I haven't?) But, yes most of your questions can probably be found by reading through the wiki. If you get stuck, come back and one of us will help you. :D

    I assumed he died, but he seems to dominate the Building Forum now.

    Indeed - but, with only a few exceptions, seemingly displaying a personality which few of us would recognise as belonging to the same person who we 'knew and loved' in this forum. Only time will tell whether that will be a lasting situation, or whether his absence from here is temporary or permanent.

    Kind Regards, John

    Hi Robert

    If you think about it, the live you have for the light fitting is required to turn the light on, so that needs to be the switched live from the switch. With me? The earth and neutral are self explanatory.

    Use terminal block or wago connectors to gang all the lives together, just make sure the one coming back from the switch goes to the lamp fitting. If you get it wrong the light will just stay on.

    Any more snags feel free to give us a shout.

    Or the fuse will blow, or other lights in the house will not work any more

    What you have is a looped in live(these are cables terminated at the central block on the ceiling rose) but the new fitting has not supplied a spare for this.
    So you require to form this loop-in live yourself, this can be done by using a connector, there many differing types available, but you should only require something that can carry 5 Amps.
    This can then be used to connect all the live loop cables together.
    So if you imagine it as four terminal positions rather than three, you would have something like this:

    Good point. I ment if the lives were mixed up though. Earths and neutrals shouldn't be a problem, especially for someone attempting this work in the first place. Must have an idea about electrics anyway.

    That is the main problem, most attempting this kind of work don't have an idea on how lighting circuits work, once they come across more than the standard three conductors, they are puzzled!
    At least Robertr6500, did not schoolboy error, by disconnecting all the conductors prior to seeking advice.

    I've never understood this. If you have a 6 amp MCB how does a 5 amp connector block become suitable?

    Surely you need a connector block able to carry more than 6 amps, i.e. the next size is 15 amp.

    PS: Having just changed the lights in my house, the design of modern fittings is terrible - the mount is so small there is not a lot of room to neatly fold up all the cables! More often than not you have a 4-way connector block housing the loop live, switch live, earth and neutral. Then the light fitting itself has a connector block so you have 2 connector blocks to sort out!

    These would be ideal for lighting connections, but there's not enough room:
