Question DetailsAsked on 3/10/2020

What size should the service wire be if the main breaker in the box says 22000 A 120/240V.

I just had Central and Air installed in my home. It is approximately 2500 square feet. the guys installing it said they think the wire from the meter to the breaker box is too small for the load. but he couldn't tell me what size i actually needed. I am trying to price the wire so i can string the wire myself then have an electrician come hook it up.

Thanks

22000A is the AIC number. You are not really concerned with this number. Most HAVC compressors take #8 or #6 wire. Read the manufacturer's instructions on the compressor for the amperage and wire size of the circuit.
