What size wire is required for a 25 amp double pole breaker for a central AC unit?

internet search will answer this. assume the distance is less than 50 feet [15 meters] unless you know it is longer. always use larger wire size if in doubt. [note: in north america, the answer is same for 220v double pole and 100v single pole ... what matters is the breaker size -- 25 amps] -- Grampa

How long is the run for the wiring?
Assuming it's a 240V circuit, the above table says 10 gauge for up to 50'. For up to 100', you want 6 gauge.
