A 20,000 BTU air conditioner typically draws around 7-8 amps. However, it's recommended to check the specific specifications of your air conditioner to confirm the exact amp draw.
Provided you use wire that is rated for 20 amps.
80% of the rated circuit. 10 amp circuit is 8 amps, 20 amp circuit is 16 amps, etc.
13,000 Btu/hr is 3,809 watts. At 120 volts that is 31 amps. At 240 volts it is still 16 amps, which is why the MINIMUM circuit you would need is 20A at 240V. This gives you the necessary "de-rating" of the circuit (80 percent) for full load bring run constantly.In other words, you could run 20A x 240V, or 4,800 watts, on a 20A circuit, but that would be the maximum load. Electrical code requires "de-rating" by 20 percent for constant loads. Reducing 4,800 by 960 watts gives you, coincidentally, 3,840 watts, which exceeds the 3,809 of the 13,000 Btu/hr.Note that A/C units are not 100-percent efficient, so the 13,000 Btu/hr will actually draw MORE than 3,809 watts. The unit will have a label telling you how many amps it requires.
A double breaker is a breaker that has 2 switches on it. One of the switches is 20 amps and the other is 30 amps.
If the 12,000 BTU A/C only requires 20 amps to run then yes you can use the same 12 gauge wire but you cannot change it to a 15 amp breaker. You will need to install a 20 amp double pole breaker. If it requires more than 20 amps you will have to replace the wiring and breaker.
There are 20 million amps or 20,000,000 amps.

usually 20 btu's per square foot so......12000 btu's should do fine
20 btu per square foot
5000 BTU's should work for a room that size.
250 watts divided by 12 volts = amps or around 20 amps
212-65=147. 147(20)=2940 btu needed is this right?

Recommended for rooms up to 20' x 20'
20hp is 50,889 Btu
20 grams = 20 000 milligrams
200 million - 200 000 000 20 billion - 20 000 000 000
