It should tell you in the user instructions or installation manual, or on a nameplate.

However, you can estimate the load by converting btu/hr into watts then dividing by the voltage you're using (e.g., 220, 110).

10,000 / 3.412.. is 2931 watts. At 220 volts it would draw 13.3 amps (or slightly more for inefficiencies in the compressor, fan, etc), while operating normally. Because this is more than 80 percent of the next-lower-rated breaker of 15A, you would install a 220-v breaker for a minimum of 16A (i.e., the next available size for your panel).

What size amp breaker for a 220V air conditioner?

The size of the amp breaker for a 220V air conditioner will depend on the specific requirements of the air conditioner. As a general guideline, you can calculate the required amps by dividing the air conditioner's wattage by the voltage (220V). For example, if your air conditioner is rated at 5500 watts, you would need a breaker of at least 25 amps (5500 watts / 220 volts = 25 amps). It is always best to consult the manufacturer's specifications or a licensed electrician to ensure the correct size breaker is installed.
