one circuit - two dimmers

I'm putting in a bunch of potlights in a basement - the wattage is fine for one circuit, but I'd like them on two different dimmers. Do I just run the power to near the two dimmers, then have the power split off to the dimmers (and out to their lights from there)? Can I just connect the three wires (power in & two power outs to dimmer) inside one of those round metal boxes near the dimmers? (Ground wire gets grounded, white/neutral wires get connected together too - or just capped off?)

How many lights and at what wattage?

Depending on the wattage you may not want both dimmers in the same box,this is for heat considerations (on the switches).

Basicaly, a 2- switch box set up----- Run the constant power (feed) to the 1st sw. box, then from there to the 2nd. Now from each swich box runyour2-wire/Wground out of the sw. to the respective lights to be controled.

This method would be true with a single box aswell, you would just omit the jumper (feed) cable between switches, For they are in the same box.

There's probably a dozen different ways to do this. If you don't have a few books on home wiring, get some, especially ones that describe projects similar to yours. Note that wiring the two dimmers is exactly the same problem as wiring two ordinary switches.

One way to think of it is this. Run power to the two switches the same as if they were two receptacles (except don't attach the white wire to the switches). Then run other cables from each switch to the lights it controls.
