Sizing An Air Conditioner Circuit Breaker Structure Tech Home Inspections If the minimum circuit ampacity says 14.9 amps, we’re good with 14 gauge copper wire. if it says 15.1 amps, we need to step it up to 12 gauge copper wire. if it says 34 amps, like in the example below, we need 8 gauge wire. again, in the case of air conditioners, we don’t need to match up the size of the circuit breaker to the wire sizes. Medium sized wall mounted or split air conditioner units with a capacity between 12,000 and 22,000 btus usually require a 20 amp circuit breaker. larger central air conditioning systems with a capacity of over 22,000 btus may need a 30 amp or higher circuit breaker, depending on the specific requirements of the unit.
What Size Circuit Breaker Do I Need For An Air Conditioner Expert 1. 15 amps: this breaker size is typically suitable for small window or portable air conditioners with a capacity of up to 14,000 btu. 2. 20 amps: most residential central air conditioning units fall into this category. with a capacity ranging from 24,000 to 36,000 btu, they usually require a 20 amp circuit breaker. Breaker size options for air conditioners include 15a, 20a, 25a, 30a, 35a. bigger 5 ton units require up to 65a breakers. most homeowners usually need help with determining the breaker size for 220 240v breakers. for smaller 1 ton (or up to and including 15,000 btu) ac units, you only need a standard 110 120v circuit with the standard 15 amp. If your unit is rated for 120 volts, then you’ll need a 20 amp circuit breaker. if it’s rated for 240 volts, then you’ll need a 30 amp circuit breaker. another factor to consider is the amperage rating of your a c unit. this can usually be found on the nameplate or in the owner’s manual. the vast majority of air conditioners will have. We have to account for the 80% breaker rule. this means that these 12.5 amps should represent 80% of the breaker amps. to calculate the size of the circuit breaker needed, we have to multiply the amp draw by 1.25 factor like this: minimum circuit breaker size = 12.5a × 1.25 = 15.63 amps.
What Size Breaker Do I Need For A 230 Volt Air Conditioner Answered If your unit is rated for 120 volts, then you’ll need a 20 amp circuit breaker. if it’s rated for 240 volts, then you’ll need a 30 amp circuit breaker. another factor to consider is the amperage rating of your a c unit. this can usually be found on the nameplate or in the owner’s manual. the vast majority of air conditioners will have.

Breaker size for 12,000 btu ac. if you have a 12,000 btu air conditioner, you should use a breaker that is at least 20 amps. however, it is best to use a 30 amp breaker for this size air conditioner. the 20 amp breaker will work but it may trip more often than a 30 amp breaker. The type of circuit breaker for an air conditioner largely depends on the specific model of your air conditioning unit. however, most air conditioners require a double pole circuit breaker rated for 240 volts, with amperage typically between 15 and 20 amps. it’s crucial to check the voltage, amperage, and maximum fuse or circuit breaker size.
