Dimmers per lighting circuit

I have a question. I see in many leviton product guides that you should use only 1 dimmer per lighting circuit. Is there a specific reason for this? Just curious, I ran a home run for some recessed lights and wall sconces and was gonna put each on a dimmer (2 dimmers) but dont want to create a fire hazzard, Thanks in advance

I believe what they are saying is that you should not use more than one dimmer per branch of a circuit, not per entire circuit. In other words, do not use more than one dimmer for each light or set of lights to be controlled by a single switch or set of switches.

If you have two switches that control the same lights (three way setup) then you can only use one dimmer. The other switch has to remain a switch.
However there are dimmers that will work with three way setups. They cost considerably more than normal dimmers.

I agree. They shouldn't mean circuit as in which breaker on the panel, but rather which bank of lights from a switch system.

Many of the sliding dimmers now work for either 3-way or single switch systems, but check the packaging. Of course, these are typ. $15 dimmers anyway.
