My question is:

Fluorescent luminaires in a commercial building are designed to be connected end-to-end. The luminaires are installed in rows in a room connected end-to-end, and supplied power for the entire row with one outlet at the first luminaire. The max. number of 20-amp 2 wire branch circuits permitted to supply any one row of luminaires is?

So if I am reading 410.65 correctly, it would be two. Does this sound right?

How about running multiple switched legs through the continuous row that are all on the same branch circuit? Some may balk at it but it is still one branch circuit.

How about a 3 phase 60 amp feeder for a compactor run through about a 100' of lights? Seen that, kind of a surprise when changing ballasts. :roll:

Really changes your plans if you are replacing the lights if you did not know it was there before you started especially to a different style of lights.
