    I need some help on wireing with a Light that has two switchs.

    I know the Red Wire connects both switchs togather this is the Travler Wire.

    But I have a Plastic Switch Box so no Ground goes to the BOX but does any Ground go to the switch?

    What do you want the 2 switches to do?

    Are they both to be used for turning the light on/off (i.e. either performs the function) as in light switches at the top and bottom of stairs?

    If so, LMGTFY.

    You've got the terminology right, the 'traveller' is the red wire. This circuit is very common
    for wiring two switches, one to enter a room at one end, and exit the room on the other
    side of it.
    Google it, and you should easily find the circuit. Any household wiring book will show
    it also. You don't have to buy the book, just find one in a home improvement store,
    and look it up.

    thanks but

    OK I sould have ask like this.

    One switch is at Top and Bottom of Staires.
    And they both work one Light.

    And I know the wireing but one thing.

    If you have a Metal Box that the switch is in one ground wire goes to the Box it's self I know this.

    But if the Box is Plastic then any ground wire will just go from the grounding Nut to the other Switchs grounding Nut am I right?

    Everybody uses plastic 'gang' boxes anymore cause they're cheaper. If you're in the States, Electrical code would require (probably) 14-2 wire (14 gauge-2 conductor), but also (maybe 14-3 for your traveller)
    inside that romex insulator jacket, will be the (uninsulated) ground wire. It doesn't matter that the box is plastic, ALL those uninsulated grounding wires have to be connected
    to one another (and it's actually 'grounded' to a pipe outside the house).
    So if I'm understanding you, the answer is 'yes'.
    All the ground wires connect to the on-off switch grounding screw (usually green), and also to the
    uninsulated grounding wires in the box. Safety requirement.
    Did I make sense?

    Ground should have nothing to do with current-carrying duty on mains wiring, that's reserved for the Live & Neutral conductors.
    Metal boxes needs to be grounded - for them to be safe. Plastic boxes can't be grounded of course - but has to be able to pass on the ground wiring to other items/outlets.

    In the UK, the bare wire in the cable is used for the earth (ground). It must be sleeved inside any box with yellow/green sleeving. An earth must be taken to any light fitting in case they have a metal case so that a fluorescent fitting or crystal chandelier is earthed.
    All earth wires go back to the fuse box and all pipes, water and gas and kitchen sink must also be earthed so that there is a common earth potential inside the house.
    Work such as this in the UK would need to be done by a qualified electrician.

    Click on "Go Advanced" it's just to the right of the "Post Quick Reply" button.

    Then you'll get a number of other tools including a tool which allows you to attach files.

    The picture shows up all-right (though it would only needed to have been 400 x 700 pixels), but the symbols are completely unfamiliar to me. Makes no sense to me.

    thanks but

    Let me just ask this first?

    If you have a Matel Box you have one Ground wire going to to Box it's self and screw onto it.

    If you have a Plastic Bix the Ground wire would go to the switch it's self?

    I ask becasu when you look on the web not one how to place shows you the ground ever going to the switch it's self?

    On an otherwise insulated switch in a plastic box there would be a terminal (on the switch) designated for grounding, but it would not be connected inside the switch.
    In other words, in a plastic housing it would just be a blind terminal meant to enable the continuance of the ground wiring to other points along the wiring route.
    It's only neccessary to connect ground to accessible conductive objects.

    In Australia you will find no earth wires behind light switches.

    This isn't relevant to anyone else, but I find it curious how wiring standards differ around the world.

    What is so difficult to understand?
    Run a short wire from the switch green ground screw to the wire nut that has all the other
    ground wires in your plastic box.
    If you don't do that, and you're in the States, and your house burns down, the insurance
    company is going to find a way to deny payment because your electrical switch
    wasn't properly grounded.
