Weekend worrier here - actually, retired guy finally getting around to all the stuff the house needs.
California's energy code requires, in new construction and remodels, either high-efficacy lights or dimmer switches*. The high-efficacy versions of the light fixtures we're looking at in the current remodel are twice the price of the low-efficacy versions (for one fixture, this wouldn't be bad, but we're putting in five). This makes dimmer switches more attractive. Since incandescent light bulbs are moving in the direction of halogen, not a terribly efficient light, my plan is to buy the low-efficacy fixtures, which take incandescents or CFLs, and put CFLs in them.
This then requires a dimmer switch rated for fluorescent lights; we'll be putting in two three-way switches, one at each door into the room.
OK, that's the setup, here's the question: looking at the installation guide for the Leviton switch, it appears that these dimmer switches do not require a neutral, just the usual hot legs (incoming and outgoing) and, of course, the equipment ground.
Is that right?
*My son and I shake our heads over this. Maybe modern dimmer switches save electricity, and we just don't know; certainly the older ones just reduced output voltage without really reducing net energy use.
