What's your experience as far as circuit size and voltage for these? I looked online and found most to be 115V 15A min circuit, cord connected. Reason I ask is I need to run a circuit for a "Future" one of these units, so there is no paperwork/unit now. I'm thinking 12/2 NM 20A should cover this. The area it would handle would be about 400 Sq./Ft. What you say? I mean I can't imagine one needing more, do they make ones that need more than a 20A circuit?

My neighbor has a 240volt 30 amp through wall AC.

I always run a 10/2 nm and then I am covered.
 
I agree 30 amp, look at the specs on this, a bigger unit will draw more.

Run a 10/3, or a conduit I have a sanyo unit similar to what you described, frankly I don't think the amperage is that high, frankly I forgot to look. I haven't hooked it up yet.

Two circuits with suppling 115V requiring a double pole double throw at the indoor unit the thrid wire is a unbroken and
used as a control wire and continual between the terminal blocks.

What is existing on the indoor unit terminal blcok is Black, White, and Red, now I'm going assuming is that the black and white
are the 115 and the Red is unbroken back and back and forth between devices.

Frankly I thought its a bad diagram because on #1 is 115V, #2 is 115V, #3 was a circuit just from terminal to terminal!
#5 and #6 is power supply circuit to outdoor unit only. It is a odd diagram to wrap you mind around at first site.

A building I am just completing has 4 of these units. 240v 30amp circ. pulled 10-2/g cord and plug. By the way most of these units have the cord on the right side if you are looking at the face of the unit
 
I'm curious, are you talking about one of those small heat pumps that only the lines go through the wall or are you talking about a heat pump that goes in like a window air conditioner (the whole body of the unit is through the wall)?

Good point could be a unit manuf. by mitsubishi or carrier. Split system and they pull very little.

No, just a through the wall AC/HEAT combo unit. Looks like I should run the 10/2 to be safe.
 
Just run a dedicated 10/2 and you'll be fine. Most I've seen are 20amp 120 or 240 depending on where. Apartments are typically a tossup between the two.
