you can always get the same power. if you have 110V/15A you can get maximum 110*15=1650W. it doenst matter if you transform it to 220V (7,5A) or 1000,000V (1.65mA). youll always get these 1650W because wattage in = wattage out.
its higher electrotechnics. but i can tell you if you have a two phase system, the voltage between two lines is (voltage to earth)*sqareroot of 3.
so if you have 220V between two lines youll get 220V/1,73=127,17V. if you want to be really safe buy equipment from europe. it runs on 220V to 240V...
well if its a two phase system (power on two wires which make 220V together) youll get 127V. its a little much i guess, your room could burn or your equipment could break. and beside youll need a neutral in awg 8.
when numbering left to right from one to five:
- lines from outlet on 1 and 3
- lines from mounting on 4 and 5
regard that youll need 230V/240V for this ballast
