Can a 12000 BTU air conditioner run on 15 amp breaker?

It is possible for a 12000 BTU air conditioner to run on a 15 amp breaker, but it may cause the breaker to trip if there are other appliances drawing power on the same circuit. It is recommended to have a dedicated circuit for the air conditioner to prevent overloading the breaker.


Can you use a 20 amp breaker for window unit air conditioner?

Yes, a 20 amp breaker is suitable for a standard window unit air conditioner. Make sure to check the manufacturer's specifications to ensure compatibility.


Is a 40 amp circuit breaker ok for a 30 amp air conditioner?

No, it is not recommended to have a circuit breaker with a higher amperage rating than the device it is protecting. In this case, you should use a 30 amp circuit breaker for a 30 amp air conditioner to ensure proper protection from overcurrent.


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.


What amp breaker for 220volt air conditioner?

For a 220-volt air conditioner, you would typically need a double-pole circuit breaker with a rating between 15-amp to 30-amp, depending on the specific requirements of your air conditioner unit. It's important to consult the manufacturer's specifications or an electrician to determine the correct amperage for your particular setup.

Can you use a double pole 15 amp breaker in place of a 20 amp single pole breaker for a 12000 BTU air conditioner?

No, it is not safe to use a double pole 15 amp breaker in place of a 20 amp single pole breaker for a 12000 BTU air conditioner. The breaker size must match the electrical requirements of the appliance to prevent overheating and potential fire hazards. It is recommended to consult with a qualified electrician to ensure the proper breaker is used.


How big of a breaker do is needed for a 5000 btu air conditioner?

A 5 ton air conditioner will need a two pole 40 amp circuit breaker to supply 240 volts over a cable of #8 copper wires. Included in this cable will be a #12 bare ground wire.


Should a window air conditioner trip a 15 amp ground fault circuit breaker when the compressor cycles on?

It is possible for a window air conditioner's compressor to trip a 15 amp GFCI circuit breaker when it cycles on due to the initial surge of current it draws. However, if this happens frequently, it may indicate an issue with the air conditioner's electrical system or the circuit breaker itself. It's advisable to have a qualified electrician check the system for any problems.


Is it possible to power a 30 amp RV air conditioner with a generator with only two 20 amp outlets by combining the two 20 amp outlets to produce one 30 amp?

No, you need a 30 amp breaker (whether that's from a generator or not it doesn't matter) with the proper voltage.


Can you use a time delay fuse in your central air conditioner of the same amp rating?

Yes, and you should use a time delay fuse.


Why would a higher amp breaker trip before a lower amp breaker?

Need more information. It doesn't seem rationale that they are protecting the same circuit unless you are substituting one for the other for a test. A unit like an air conditioner may have multiple breakers and a higher value breaker may trip because the load it is connected to is drawing current in excess of the rating of breaker.


Would replacing an old 15 amp breaker stop the air conditioner and fan from throwing the breaker?

It is possible that replacing the old 15 amp breaker with a new one could resolve the issue of the air conditioner and fan causing the breaker to trip. However, it's also important to ensure that the electrical load from the air conditioner and fan is not exceeding the capacity of the circuit. If the problem persists after replacing the breaker, it may be necessary to consult with an electrician to assess the electrical system.
