    Hi!
    I don't know if this is the wrong place to post this.. if so,
    sorry. I'm hoping someone here can help me..
    I'm trying to install a dimmer switch in my dining room,
    which previously had a regular lightswitch.
    So, inside the wall box, there are two bundles of wires.
    One has black, red, white, and bare wires, the other has
    black, white, and bare. I'm assuming the white is neutral,
    and bare is ground.
    Anyway, the configuration looks to be a 3-way switch, but
    there isn't another switch that controls this fixture.
    SO.. I wired the switch according to the instructions for the
    3-way, since this was the only wiring configuration that had
    the 4/3 wires in the wall box.
    I should add that the dimmer switch has a black wire, a green
    wire, and two red wires.
    When I wired it according to the instructions, the dimmer worked
    fine, dimmed the light.. only problem, it dimmed the BATHROOM
    light. (The bathroom and dining room are on the same circuit.) The
    dining room light didn't come on at all.
    Can anyone help me out here?
    Thanks in advance!

    Hmm.
    Okay, another dumb question.. what do I do with the black wire from the
    b/w/r/b cable?
    Just cap it off?
    Thank you very much.. it's sad, I'm in eng. school right now (computer, not
    ee)..
    I can wire a breadboard, but I can't replace a lightswitch!

    Hahahaha., nevertheless it's been handled quite nicely i would say

    & Amy no-one is born all knowing, plus, the number of professionals that
    don't know or dare to do a thing about household electrical wiring is
    staggering };-) Roy

    Nah, it isn't rocket science.
    There is a need to take precautionary steps though. Start by getting a
    good multi-meter and ALWAYS check that you have the power removed before
    doing anything.
    Some other advice: If you must work on live power, or it is for some
    reason unknown if the power is off, keep one hand either in your pocket
    or grab the back of your jeans, if possible. It's a learned skill, but
    one that results in you living another day.
    Lay out the circuit in your mind or on paper. In pre-existing residential
    wiring, you are liable to run up on all kinds of wierd things. Tracing
    out the circuit with a multi-meter is sometimes a required hassle.
    The most important thing is to just make sure the power is off.

    You can't 'idiot proof' anything....every time you try, they just make
    better idiots.

    Not necessarily..
    The old switch had two screws on it, the new dimmer has four
    wires.. the old switch wasn't even grounded, the bare wires
    were just capped off.. So, I don't think it was wired correctly
    to begin with, plus, it was an entirely different type of switch.
    But thanks.

    Power was definitely off.. I'll admit I'm a bit clueless, but not THAT bad..
    anyway, it's working perfectly now.
    Thanks everyone who replied!
