In article 220, the load calc for track lighting is done based on the total feet installed, but there is no limit to the installed luminares on the track.

Heres a new product that limits the installed load to a specified amperage:

as I recall I used to do a lot of large department store work and at one time I read the instructions with the track lighting I was installing and it said it was for a max of 1200 watts yet the stores would load up 20 ' or more with a million heads and the track would burn up and we would go out and replace it over and over and over. But I do remember that there was a max wattage for the track in the instructions at the time I was installing it.
 
Is this it?
