I am color coding each breaker and will be using harness with Anderson connectors. Each breaker capacity is identified. These are not switches. If a breaker overloads and breaks the circuit, just push down on the white dot and the breaker will reset.

HVAC guy came yesterday and verified that there is refrigerant in the system. However, the system did not start up. We are getting Code 6 & 7 errors which seem the be related to communication issues not power. Working on it.. Me HVAC said that it should start up if we get the communications right.

Found out that the 3 wire communications cable was never installed and that harness is missing. We had to wire the units ourselves and the two heat pumps started up and ran great.
It was around 74° today, so we had to set the temperature down to 68°. They ran strong, cold and quietly.
The only fly in the ointment was that one of the outside compressor units had a label that said that is was 24 volts not the 48 volts we are providing. We took the units enclosure off and verified that all of the components are 48 volt.
Can you believe that someone put the wrong label on!
Calling up the hvac guy to top off the refrigerant and fine tune the system.
I can't believe how cold the air is and how quiet.
It is a dream fulfilled.

I forgot to mention that those black rectangles above the white breaker buttons are actually white letter on black labels, so that each circuit can be identified. No looking up for a list somewhere.

You've anticipated this day for many years, the completion of your mini-split house + cockpit A/C system that's all DC-powered. Congrats!
