Trouble with Electric Circut

I am trying to make a proofing box for bread making, and have run into a small snag. When I try to adjust the electricity going to the light bulbs in the box with my dimmer switch nothing happens, also when I try to turn the light bulbs off with the rheostat it trips my circuit breaker. I am using 4 7watt 120volt bulbs arranger in a parallel circuit, which are connected to a 600watt dimmer switch. If anyone knows what I am doing wrong I would appreciate the help.

. The switch/dimmer goes in series with the load, not parallel.

I have tried both ways already with no success.
. And the lamps need to be in parallel. Confusing, huh? . OK, connect the hot wire from the wall to one side of the dimmer. Connect the other side of the dimmer to one leg of each lamp. Connect the other legs of the lamps to the neutral from the wall.

Okay, I did what you said and it has stopped tripping the breaker. However, I still cannot dim the lights. Any ideas?
. You have a 28W load on a 600W dimmer. Add more lights (150-200W ought to be enough). If that doesn't work, I suspect you've blown the dimmer. Or get a dimmer rated for fewer watts

Can you recomend a dimmer switch I should buy, or of a way to modify the one I already have?
does it work when you connect it to mains in series with high watt incandescent or halogen bulb ? if yes the load of 4 small lights is too small if no the dimmer is bad
. A quick search shows that 600W is the standard size for dimmers. . Any dimmer should "work." Even if the load is not great enough for the dimmer to function properly, you should still have some operation, even if it's pretty much on/off. If you are getting no reaction, I suspect the dimmer is bad. Try it with a 100W incandescent light bulb.

I just did a few tests with the dimmer, and it is definitely bad. Thanks for everyone’s help!
. It's been a while since I worked with dimmers. I can't remember if the dimmer needs to be wired with one particular side hot or not. If so, it should be marked on the dimmer somewhere or check the docs that came with it.
