high wattage 3 way dimmer


So we installed a chandelier that has 9 lights, each with a max rating of 100w, so i guess 900w.

The house is wired to have a 3 way switching (on/off and on/off/dimmer).

The dimmer gets really hot, so I'm betting we're overloading the dimmer switch, but I'm not sure what's the rating for the switch is.

My question is will a 1000W dimmer/3 way switch be sufficient to carry the load? Do I need to go higher, if so does a dimmer with 3 way capacity exist?

We're not going to ever switch out the light fixture.

Thanks

The dimmer gets super hot, so I'm betting we're overloading the dimmer switch.

Ouias ( Yeah ) there is a bigger dimmer on market is 1000 watter and 1500 watters but there is a nice gotcha is that you have to mount them it own switch box if you have other switches it will not work due it have pretty good size heat sink to keep the dimmer cool so let moi post the photo what it look likes.



That one of few style it will come with heat sink but I know there is a model that do not have heat sink but you will need to use the metal switch cover to get it working properly without getting overheated.

Costwise I am not sure what they are running for but I know the last time I brought one for my customer it was about 100 Euros ( Dollars ) but you can check around some of the big box store if they don't have it. You may have to order it or get it from electrique supply centre.

Merci,
Marc

Lutron makes a 1000 Maestro dimmer that fits in a single box. As long as it is the only device in the box, it does not have to be derated.

Even a properly sized dimmer will get warm to the touch.

The dimmer rating might be stamped on the mounting strap.

Did you ever think of installing lower wattage lamps? Do you really need 900 watts of light in a room? By installing 60 watt lamps alone, it will get you into a 600 watt dimmer. As long as you don't need to derate the dimmer.

I thought you had to size the dimmer based on what could happen. ie someone else moves into that house, sees that they can put 100W bulbs in and overloads the dimmer.

What if I install a 600 watt dimmer then someone changes out the fixture for one requiring a 1000w dimmer? We don't do what if's...

Big difference between changing out a fixture and a homeowner using 75W bulbs instead of 60W bulbs.

So it's a single box, so the 1000w would fit.
Thanks

We dont know for sure if you are overloading your dimmer,
What is its capacity ?
Any dimmer handling such a load would get quite warm,
some even hot,
depending on how and where it is mounted.
Modern electronics are rated for 75 degrees celcius
so its probably no where near that temp,

Try using a metal mounting plate to help dissipate the heat,
and expect it to get quite warm, its normal !
