Electrical Question from Lori about 220 Volt Air Conditioning Wiring
Background: Lori, a Homeowner from Chicago, IL

Question: 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!

Dave’s Reply:
Thanks for your electrical question Lori.
Hey 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.
