The breaker size of a Daikin air conditioner will depend on your specific unit and its minimum ampacity size and voltage requirements.
Daikin has been producing air conditioners and other appliances for a long time and has developed some notable core technologies. However, since the brand is so established, there is a wide variety of air conditioner models.
Fortunately, you can determine things like the right breaker size for your unit by consulting the label on the unit for the correct amperage and voltage requirements of the unit.
About Daikin air conditioners
Daikin was founded in 1924 and since then, it has expanded its operations into 160 countries across the world.
Daikin is also the largest HVAC manufacturer in the world and has products that range from heat pumps to central air, mini-split, and complete HVAC systems, which are all made in the USA.
Daikin attributes its success in the air conditioning and heating field to the three core technologies that are incorporated in Daikin products, namely, heat pump systems, efficient inverter technologies, and better refrigerant control.
All of these technologies, when paired with their all-aluminium evaporator coils and 12-year warranties, have made the brand a favourite amongst consumers.
What is the breaker size on a Daikin air conditioner?
Since Daikin has such a large variety of products in their different air conditioner ranges, it can be difficult to determine what size breaker you need for your unit.
It is important that you find the right size circuit breaker for your Daikin air conditioner, because a circuit breaker that is too big can fry your electrical system and can have some serious dangers.
When you are installing any air conditioning system in your space, there are three main factors to consider, namely, finding the right capacity for your space, the voltage required, and the amperage required for the circuit breaker.
If you are focusing on the necessary amperage, this will be based on the BTU capacity of your air conditioner.
General guidelines when it comes to the breaker size of Daikin air conditioners starting from the smallest 9000 BTU size, as with this DAIKIN Wall-Mounted Ductless Mini-Split Inverter Air Conditioner Heat Pump System, which operates at 230 Volts, include:
| Air conditioner capacity | Minimum circuit ampacity size |
| 9000 BTU | 15 Amp |
| 12000 BTU (1 ton) | 15 Amp |
| 18000 BTU (1.5 tons) | 20 Amp |
| 24000 BTU (2 tons) | 25 Amp |
| 30000 BTU (2.5 tons) | 30 Amp |
| 36000 BTU (3 tons) | 30 Amp |
However, this is just a general guideline and it may differ for each Daikin air conditioner model. The voltage of the circuit is also important if you want your air conditioner to function properly and safely.
There are also signs that you can look out for, which can indicate that you have the wrong size circuit breaker for your specific Daikin air conditioner.
How to find the minimum circuit ampacity for your Daikin air conditioner
If you want to find the minimum ampacity that you need for your specific Daikin air conditioner model, it is best to look for the label on the model itself, as each individual appliance has its own electrical requirements.
This label can usually be found on the side of your outside unit, or on the inside of the interior unit, and it will list all of the electrical requirements for your unit, including the minimum circuit ampacity and the voltage required for your unit to function as intended and safely.
It is worth noting that you may need a wrench to unscrew the bolts on service panels to find the electrical label on your unit. Make sure that the unit is turned off and that the breaker is switched off before you remove any service panels.
How to find the right voltage for your Daikin air conditioner circuit breaker
The voltage of the circuit breaker for your Daikin air conditioner also needs to match the requirements on the label.
Since the power in your house needs to travel from the main box through wires to the various electrical appliances, this can cause what is known as volt-drop.
However, most appliances are designed with this in mind, and you only have to worry that your circuit breaker is able to handle the voltage specified for your Daikin air conditioner model.
How to know if you have the wrong size breaker for your Daikin air conditioner
If you are concerned about the circuit breaker size for an already-installed Daikin air conditioner, there are a few warning signs to look out for, which can be an indication that you have the wrong size circuit, including:
- A burning smell coming from your breaker box
- The breaker becomes too hot
- The lights are flickering
