Don't worry. It's mostly questions such as the following that get the scathing remarks. Requests for info that is are clearly stated in the machine's manual(s). Lead additives for unleaded fuel, single weight Vs multi weight oils, oil change intervals and detergent vs. non detergent oils.

I assume this AC system is setup 40ft from the building’s power distribution panel?
There must be a resistive heating system built into the inside evaporator unit when it rated for 60.0 Amp? I wonder what the 30.0 amp is for? That's an awful large fan? Is this a water sourced heat pump or something?
Most electrical codes and common sense requires a single isolation point be able to de-energize the whole AC system.
Depending on which loads are motors and if they are centrifugal fans, scroll compressors or reciprocating compressors. The starting inrush current amount and duration of the inrush affects breaker and wire size.
This maybe a situation where a common supply over to a main disconnect and local breaker panel right at the AC unit maybe required?
Getting into wire this size I like to run it in conduit. It's certainly not any more expensive and it's well protected. Measuring a string pulled through the conduit then cutting the wire to length right off the venders rack reduces waste/$$$.
Just depending, driving a ground rod(s) right at the outside AC unit maybe required or just a good idea. If trenching conduit into the ground, laying the bare #6 ground cable in the dirt works very well.
