Hello,
Looked thru the Trane and Carrier web pages, but couln't find any specifics on this.
For a central residential air conditioner, a pretty basic non-high efficiency unit, of 3 tons, what is "typically" the current draw ?
Are these for 220 V ?
Thanks, Bob
The outdoor unit runs about 10 amps, at 220 volts. Depends a bit on the model, and how recently and how well serviced. But, that's in the ball park.
If you need to know because you are sizing the circuit to feed the A/C, you need precise info which includes not only the compressor but the condensor fan motor as well. The mfr will stipulate the minimum branch circuit size and fusing requirements.
Yes, residential units run on 240V.
A "typical" 3 ton unit might draw 16.5 Amps plus maybe 3 Amps for the condensor fan. The blower for the air handler adds more, but likely on another circuit.
Post more info about what you are looking for.

Hmmm, My Carrier 3 ton unit is fed with 20 Amp 220V circuit. Using 10/2 copper wire. Distance from panel to unit is less than 10 feet.
What does the nameplate rating on the unit say?
Hello,
Thanks to all for info.; appreciate it.
Very old unit from previous owner. Nameplate unreadable, other that it is apparently a 3 ton unit.
