I'd like to make myself a lighting control that would schematically look like this:
I don't know a lot about dimmers, but I heard they have some parameters which might prevent them from working. I'd like to have three dimmers, two of which would control their own branch of lamps (incandescent only, I hate all other lamps atm), and the one that would control both. I assume all dimmers have an option that completely cuts power, because I need that at least on the main dimmer (leftmost on the picture).
What kinds of dimmers (exact parameters are welcome) do I need to use with a maximum of five (on each branch) 75w incandescent lamps?
I wouldn't like this question closed, so I'm adding that this should not only work with exactly (5 + 5) × 75w incandescent lamps, but a maximum of that quantity to include all variants with less lamps, as I believe it should work with equipment required for maximum load (but I am prepared to be corrected on that).
