Air Conditioning - Electrical Whip

With the help of everone here I finally made a decision to go with the Carrier TXA 13 Seer unit. The question I have prior to installlation is the Electrical Whip and circuit breaker box. What guage wire should be used from the breaker box to the condensor/compressor? Also what guage for the ground. Additionally, what breaker box should be used I like the small pull down handle, but don't know what is best. Any suggestions?

With the #### you give just tell that its a SEER of 13 that dont say how big how many ton .it is at all The TXA can be just part of the model. The paper work that comes with the unit will tell you what wire and breaker size that you need.

The existing whip has 8-guage red s/b black (cracking) with the ground being #10 guage red also s/b green. Here's the strange part the outside breaker box to the AC unit has a 60-AMP box wired to the main panel that is 40-AMP this is for the 2-Ton unit.

In looking at the tag it states "Max CKT - BKR (*) 20" / 20-AMP*2 (220V) = 40AMPS for the unit but the box is 60AMP wired to a 40AMP main panel. Don't they need to be equal. Also, I'm trying to find out the required amp for the new unit, but wanted to see if my logic is correct. Again, I want to thank everyone for their help on this project. Thanks again.

The heaviest breaker you should use is what ever is marked on the outdoor unit. If that is 20 AMPS, do not use heavier than 20 amps. The wire should be at least 12 AWG for a 20 amp breaker. Heavier wire is fine but no lighter. Unless required by local code, you do not need a breaker both indoors & out for the same piece of equipment. But there must be a means to disconnect the power within 5(?) feet. of the outdoor unit. I normally use an unfused, pull-out disconnect.

Grady,
Thanks for the information can you make a recommendation as to the name of the box you use and model #? Thanks.

For outside by the unit just ask for a weather proof unfused disconect. The pull out kind .They cost less and do the job.
