Calculating Total Current for 40x 2000W Metal Halide Floodlights at 380-415V Stadium Setup

hello , 

I need your help 

If i have 40 lumminares for stadium lightning, each pole contain 10 lumminares, 

each lumminare is 2000w , 380-415 volt, 10.3 ampere , 

each lumminare have a ballast conected to ignitor connected to the lumminare. 

what is the current needed ?  3X160 ampere ? 

 

and also , i dont anderstend : 

1. each luminare take 10.3A in order to work? or its just the initial current ? 

2. becouse only two phase is connected to each loumminare so the current is split between the phases ? and each phase current is 5.15A ? 

3. each pole need 10.3A X 10(lumminares) = 130A in order to operate ? 

i added the files for this lumminare and his equipment.

thanks ..

Hi

Where is the 160 coming from? First, the 10.3 A is a the operating current. It will not working properly if it is not supply with that rating. Current is constant in a series connection. Second, you need to understand what three phase is. ( http://myelectrical.com/notes/entryid/8/three-phase-power-simple-calculations )
