    Default Light switch for tungsten halogen light

    Hi Guys,
    First post here and thanks in advance for your help. I have installed a tungsten halogen flood light for my deck area. I want to run the wiring to the light switch area in the laundry and replace the 2 gang switch with a three gang. As the current light switch does not have any earth connection, where should I run the earth to from the floodlight.

    Thanks

    Could you please provide more info please, such as;

    1] wattage of lamp.
    2] location of the light fitting (weather) & the material upon which it is to be mounted.
    3] is a "J-box" able to be mounted anywhere near the light fitting? The J-box must be accessible at all times.
    4] cable distance from light switch to light fitting.

    I pinched this diag from an earlier post. If I was doing this I would wire it up like this diagram.
    Firstly the switch; L is loop and this terminal goes nowhere it is only a suitable terminating point for joining wires of the same potential together. C and 1..... OR..... C and X are the two switch terminals that make or break the circuit, it is normal to use C and 1 in this situation as in the diagram.
    Next the light, I don't know what your floodlight looks like but it should have some sort of barrier or terminating strip for making connections. In this diagram they are represented by E(earth), L(loop) which has the same function as on the switch and 1 and 2 which are the connection points for the halogen globe.
    As you can see from the diagram there is no earth going to the light switch, earth goes directly to the flood light itself to earth the flood light body. If you can't figure how to do it with this diagram then I would seriously consider getting a sparky, it may not be as costly as you think and would also give you peace of mind which is worth a great deal

    Hi elkangorito, in answer
    1 150w
    2 outside undercover and brick wall
    3 No 'J box"
    4 About 21/2 - 3 m down the wall into the inside of the house

    There is only a 3 terminal strip with Active, neutral and earth for the light.

    Thanks.

    Just one last question netdevil.

    How experienced are you at doing electrical DIY? Do you know what "BP connectors" are?

    I ask this because in order to do the job properly, you'll need to know certain things. Also, by you knowing certain things, we won't have to go into lengthy & detailed explanations upon how to do certain things.

    You will probably find that the power and earth for the lights runs through the ceiling; what you are (probably) seeing at the wall switch is the active and switched active. (it'll be something like a red/white wire pair).

    You'll need to extend power and earth from one of the existing light fittings, snake it through the roof to the new light, then pull a switch wire (red/white pair) back to the new switch on your wall plate.

    Abominable, poorly labeled picture below. (geeze, you'd never know that I have worked as a designer...I'm blaming Paint.) The grey line is the white wire...just think of it as a dirty white! (see also familyguy's pic.....but the L terminal may have to be a BP connector in your case.)

    Hi mate,
    If it has a lead on it, plug it into a nearby power point. That way, it would be legal (sort of) and easy to do!
    If you want it on a switch, which of course you do, you need to understand basic wiring principles. Whatever you do, connect the earth wire!
