Correct wiring for dimmer controlled recess lights

I'm installing 12 (recessed) cans in a basement remodel and was intending to use 2 600W dimmers (6 ea) on the same circuit. The lights will most likely either be 65W or 75W. The circuit is 15A with 14-2 wire. Will this work?

Also, am I asking for trouble if I run more than 6 cans on a single 600W dimmer? I've heard that installing a 1000W dimmer doesn't necessarily provide any brighter light.

FYI, I've not yet purchased the dimmers nor the cans.

Thanks,

Mike

Mike: I believe you will find the can lights will limit you to about 60 watts. 6 per dimmer is fine. A 1000 watt dimmer isn't meant to make the lights brighter, just allow you to put more load on it before it melts. At 65 watts per light you will be pulling about 6.5 amps so you will be ok with the 15 amp circuit and 14-2.

Thanks for the input. Due to the setup of the room (it is "L" shaped), I may even go with 3 dimmers - putting 4 cans per dimmer (again all on 1 circuit). That way I can control one section of lights at a time.

hey...I just heard something that if you put multiple dimmers in the same box, the wattage drops. True, not true? I'm on my way to Lowe's to check out some Lutron dimmers. My plan was to have 3 to 4 in a single box. Guess there's some tabs or something that you need to clip off in order to fit more than one.

thanks........

yes that is true and the other thing to head up is the box size as well you have to watch it some of the dimmer will take pretty good part of room in the switch box.

just follow the manufacter instuction very carefully pretty good percentage will give you a head up if you have multi dimmer in the switch box.

this example which i know one brand i used pretty often and if the dimmer rated at 600 watts if you break off one tab then it will reduce to 500 watt if break off both tabs it drop to 400 watts rating

this is a example what it will happend when you get two or more dimmer in two or more gang switch box.

Merci,Marc

thanks.....if I go with 4 cans per dimmer, I can break it into 2 double gang boxes. One box with 2 dimmers and the other box (right next to it) 1 dimmer and 1 switch.

Merci,Marc
