The breaker you use is determined by the size of the wire in the wall not by what is being connected to that circuit. If you have 14/2 wire then use a 15 amp breaker. If you have 12/2 wire then use a 20 amp breaker. The breaker protects the wiring not the item connected.
For a 1.5 hp air conditioning unit, it is recommended to use a circuit breaker with a rating of at least 15 amps. This will ensure that the breaker can handle the starting current surge of the compressor without tripping. It is important to consult the manufacturer's specifications for the exact breaker rating required for your specific air conditioning unit to ensure safe and proper operation.
Breaker sizing is dependant on what the load amperage is that the breaker is connected to. If the amperage is not given but just the wattage, use this equation I = W/E. Amps = Watts/Volts. This air conditioner unit should be on a dedicated circuit receptacle. On these types of loads the conductor can only be loaded to 80% of the conductors rating. So a 15 amp breaker times 80% = 12 amps or Watts = Amps x Volts, 12 x 120 = 1440 watts. A 20 amp breaker times 80% = 16 amps or Watts = Amps x Volts, 16 x 120 = 1920. Once the breaker is sized remember to use the correct wire size to correspond with the amperage of the breaker.
You should not have to calculate the watts of the unit. All the information that you need will be on the nameplate of the unit. It is this information that electricians use to calculate the conductor size and breaker to supply the power to the unit.
"Air" and "Vacuum" describe how the breaker extinguishes the arcing current. An Air breaker opens far enough that the dielectric strenght of air is enough to extinguish the arc. A vacuum breaker's contacts are in a vacuum. Oil breakers use oil. SF6 breakers use SF6 gas to extinguish the arc.
The fuse (or circuit breaker) rating has been exceeded. I'm assuming you do NOT have the AC unit connected to a dedicated circuit. Lets say you have a 15 amp circuit breaker and the AC unit draws 12 amps and other items on the same circuit draw an additional 5 amps. The total amp draw of 17 amps exceeds the circuit design capacity; so the breaker trips to prevent an electrical fire. If you have old style fuses, NEVER EVER replace a fuse with a higher rated one! I'm sure you'd have problems with your homeowners insurance paying out when your house burns down. Have an electrician run a new dedicated circuit for the AC unit and you should be good to go.

The breaker you use is determined by the size of the wire in the wall not by what is being connected to that circuit. If you have 14/2 wire then use a 15 amp breaker. If you have 12/2 wire then use a 20 amp breaker. The breaker protects the wiring not the item connected.
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.
There is no reset button on a central air unit, there is a small breaker or fuse box outside next to the unit, it is possible the fuse is blown or breaker tripped.
For a 1 ton air conditioner unit, the circuit breaker size typically ranges from 15 to 20 amps. The exact size needed will depend on the specific model and requirements of the air conditioner, so it is best to consult the manufacturer's specifications or an electrician to determine the appropriate circuit breaker size for your unit.
A Rheem RALB36JAZ air conditioning unit typically requires a 30 amp circuit breaker to operate safely. It is important to match the amp rating of the breaker with the requirements of the unit to prevent electrical issues and ensure safe operation.
The Energy efficiency rating for the LG 3850 BTU Air Conditioner/Heater unit is 9.7.
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.
Amp Interrupt Rating
No, a 100 amp breaker is not sufficient to handle 5 air conditioners. Each air conditioner typically requires its own dedicated circuit with an appropriately sized breaker based on the unit's electrical requirements. You would need multiple circuits and breakers to safely power 5 air conditioners.
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.
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.
