OK, before I blow something up....

I'm trying to replace a light switch with a dimmer switch and things don't look quite like I expected, and I'm not sure exactly how to hook this up.

There are 3 sets of wires coming into the box - each with a white (neutral?), black (hot?) and bare copper (ground). The 3 white wires are twisted together and not hooked up to the switch in the box, the same w/ the 3 copper wires. The three black wires are connected to the current switch, one to one of the screws on the side, and the other 2 pushed in the connections on the back. There are electrical outlets in the same room and in a different room on the same breaker.

Now, on my dimmer (single pole), I have 2 blacks and 1 green (for the ground). I'm not sure exactly how this is supposed to work but I think I need hook 2 of the black wires from the box to one of the blacks on the dimmer, and then the other black to the other black on the dimmer - then run the green to the ground wires that are twisted together......

Or.... I have no clue.....

Thanks for any help.

All you are doing is substituting the dimmer for the switch. the one wire on the bottom screw must be your load terminal. the other two blacks up top [one is the hot, one continues the hot to another part of the circuit] are spliced together with one dimmer wire. the bottom wire splices onto the other dimmer wire. the green is the ground and goes with the other three bare wires.

That worked, thanks!
