    This is a question that may offend the reader because it is so
    incredibly basic, but my deep ignorance and fear of setting off a fire
    compels me to make this inquiry. The floor dimmer box on my halogen
    torchiere died. I noticed that I could probably just cut the power chord
    where it enters the dimmer box, and install a plug to resuscitate the
    lamp. But then I noticed that the dimmer box comes with a fuse. Since
    I've heard that halogen lamps are rather accident prone, I wonder
    whether the fuse is a necessary safety measure for the whole lamp, and
    not just for the dimmer box. Would I be creating a fire hazard with my
    proposed repair, just putting a plug on the power chord?

    Thanks so much, and apologies again for asking such a simple question.

  2. No problem about basic questions.

    First question would be: Are you sure that all that's in the box is a
    dimmer and not also a stepdown transformer? If there is a transformer,
    doing what you suggest might result in much more than just a blown fuse.

    If it is just a dimmer, then what you are suggesting would be fine but
    do include a fuse of the same type.

    How can you tell it's just a dimmer? In a dimmer, there would be the
    pot for adjustmnet, a 3 legged semiconductor called a triac, and fewer
    than a half dozen other small parts.

    See the FAQs on appliance repair for more info.

    Assuming you are in the US, the whole assembly is UL rated. If you modify it
    it isn't. This can cancel your insurance. Also, is the lamp 110 VAC or 12
    VAC?
