1800 Watt dimmer question

I need a dimmer that can handle 1800 Watts of
incandescant lights. All the 1800/2400W dimmers I'm
finding available are rack mounted units mainly for
DJ use, which is more than I need.

Any ideas where I can just get a standard switchbox mounted
1800W dimmer?

Thanks

Since 1800W at 120V is 15A, the TRIAC doing the dimming would dissipate
about 15W full on, which is a lot of heat to get rid of in a standard
switchbox.

My guess would be that you won't find one.

Is it possible to parallel triacs? Seems like it would be possible, but I've
never tried it.

Just a silly question. Seems like it would be useful.

Leviton, and many other concerns make 1,800 W dimmers that will "kind of"
fit in a standard switch box. They are commercial models that usually have
heat sink fins as part of the cover assembly. The "kind of" part is due to
the size of the heat sink assembly. If the installation is a SG box it will
work fine. If it will be installed in a box larger than SG, and next to
other switch devices you need to break off a portion of the fins, and the
rated wattage capacity must be reduced accordingly.

There are a number of wall mount dimmers on the market that will handle very
high wattages. They do not mount in to the box as a standard light dimmer.
They have large heat sinks on the sides to dissipate the heat. The main body
of the dimmer will fit in to the box, and electrically connect up as normal.
The heat sinks are necessary to dissipate the heat that the internal
components make. Leviton is one of the manufactures of this type of switch.
You will most likely have to go to a supplier for professional electrical
installations to get one of these. They are not inexpensive, so don't be
surprised that you will have to put out some cash for one of these. About
10 years ago, I installed a 1200 Watt dimmer in our dining area for the
chandelier. It works very well.

Thanks for the info.
It doesn't need to fit into a switchbox; I can deal with something
a little bigger - I just don't need the expensive rack mount dimmers
I'm finding that are designed for 1800/2400 watts.

I'll check out Leviton.
Thanks
