[ad#block]Question: Is there an adapter that I can use for my new 230-volt 15 amp Air conditioner?
I have a 20-amp 220volt line in my house and can only find a 15-amp air conditioner! I am hot! Is there any kind of adapter that will allow me to plug my new 230-volt 15 amp AC into my existing 220-volt 20 volt plug? Thanks very much.
Additional Comments: It’s excellent!

230 Volt Air Conditioner
Application: 230 Volt Circuit for an Air Conditioner.
Skill Level: Advanced – Best performed by an Electrical Contractor or a Licensed Electrician.
Tools Required: Electricians pouch of hand tools, voltage tester and protective safety gear.
Estimated Time: Depends on the make and model of the panel and the condition of the existing electrical circuit breakers and wiring methods.
Precaution: For safety the main circuit breaker should be turned off or any other disconnect means that would deenergize the panel before replacing a circuit breaker, however turning off the main circuit breaker may not deenergize all of the areas of the panel components and wiring. This is an extensive project that requires experience and should be performed by a Licensed Electrical Contractor.
How to Wire a 230 Volt Air Conditioner
- Hi Lori, let’s get you cooled down! All that is needed is to convert the existing circuit from 20 amp to a 15 amp.
- This involves replacing the 2-pole 20 amp circuit breaker with a 2-pole 15 amp circuit breaker and replacing the 20 amp outlet with the appropriate 15 amp 220 volt female outlet that matches the male plug that came with the air conditioner.

Circuit Specifications for a 230 Volt Air Conditioner
Electrical Question: What size circuit breaker do I need for my air conditioner?
- I need a 2 pole 20 amp breaker for my panel box.
- The breaker will be used for the wire to my air conditioning unit.
- The specs are:
- Rated voltage 208/230.
- 1 Phase, 60Hz.
- Min. Voltage 197, maximum voltage 253.
- Minimum circuit ampacity 18.9.max. fuse or circuit breaker, 30 amps.
- I was told that on the 12/2 wire I need a 20amp breaker, but in looking at different 20 amp breakers I see also other numbers, such as Q22o etc.
- Can you please tell me what is the proper breaker for me to use.
Thank you,
Kevin
