A/C Specs For Central Residential Unit (evap. located in hot air furnace)
 

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

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.
