Question:
Answers:
Tonnage has nothing to do with it. What make, brand, model. All the information you need is typcially on the side of the unit. Whether it is 110 (not likely), 220 or 3phase. Need specifics.

30 amp double pole breaker w/ 10 wire. it will say on the inside cover of the unit but in past experience, 30 is sufficient.
ok, i assumed you were american bc you used a standard american size i.e. ton. i dont know what european ppl use for their sizes of air conditioners. someone gave me a thumbs down for what reason i dont know other to be funny i guess. i m an hvac service tech and i do know how to size a breaker thank you very much.
use copper, not stranded aluminum. your unit has a capacitor to help w/ startup surge
