Nic-- you need to ask a question otherwise I will close this thread. Tells us what you want-- we do not charge for help here.
How have you tried to solve them? We will not just answer your questions, you will need to show us the way you have tried to solve them, we will critique them and show you where to look for the answer.

Ask the question and perhaps we can direct you to the articles. From there you can try to answer them. Paying for answers is not a way to learn IMO

For an A/C, you need to look at the MCA and MOCPD on the nameplate.
Search for "MCA" in your code cycle to find relevant articles.
If you choose the breaker size equal to Max OCPD and it still will not hold for starting you have excessive VD or a defective installation.

Where have you looked for an answer so far, and why did you look there?
I'll give you two clues for key words you should be looking for - Air conditioning equipment and overcurrent protection, and maybe expand the meaning of overcurrent protection to include short circuit and ground fault protection.

The way I do these questions is that I look for a few items in the question and match them to something in the NEC. For instance a/c--would be a clue since art. 440 is for a/c units. Now that article is broken down into many parts. The next important part of the question is overcurrent protective device or branch circuit protection. This is a little tricky because you may not be familiar with the terms in the code. You need to look for the section- there are 7 in this article- that deals with branch circuit short circuit and ground fault Protection. This is considered your branch circuit protection.
