I dont have too much experience with air conditioning and I have a few questions about properly designing the installation of 2 new 5 ton AC compressors going in place of one 10 ton. The new units are 3 phase, minimun circuit ampacity is 24Amps and the max breaker size is 40Amps. Any info or code references would be helpful. .
Do i need to have a 40 amp breaker to handle any inrush current or do i size the breaker based on the wire size needed to handle the min. amps (24) for my application?
Also I have an existing 1" run of EMT feeding the old unit that i would like to pull my new circuits through, would i still only need one ground sized to the largest conductor in that pipe?
This is something i was never really sure about and i am starting to do more AC units and want to make sure I am doing whats best. thanks
