As a P135 pilot - you probably won't be allowed to reset a CB without maintenance guidance.
As far as emergencies. follow the POH - step by step.
Certainly doesn't sound spoon fed, but if many lower time pilots have succeeded before you, I'm sure that you will be up to the task at hand if you put forth the effort.
The purpose of systems knowledge beyond just being able to reset a breaker is to understand the possible failure modes, and to give you the ability to speak with MX about EXACTLY what is happening, so the problem can be fixed the FIRST time....
Sometimes an incorrect indication is more dangerous than a system not working, and knowing a system and what can happen when it fails is important.
A simple, it doesn't work write-up is ok, but to understand the system in enough detail to have a discussion about it with a mechanic is invaluable in getting the item fixed, and back in service.
Additionally, a deeper understanding of a particular system will give you more insight into how it MAY interact with different systems....
Under 135, you may not have a mechanic at every stop, and on some routes, it possible to go 5 stops before going to a base with a company mechanic.... knowing the airplanes systems in detail so you can pass the correct info to mx control to get a part and a mechanics enroute in an AOG situation while on a scheduled route is very important.
135 is NOT just sit down, strap in and fly job like 121...that's why some people LIKE 135...There is judgement involved...it's not flying with a yes/no flowchart.
It's going out, and as the the previous posters have shown, running numbers, doing charts, math, weather, flight plans, etc, with some help from dispatch, but understanding they don't DO IT FOR YOU LIKE 121.
You are often showing up at an FBO, with a suitcase and a "mission", then figuring out how to accomplish the trip safely. It may include getting a plane hangered or DEICED, fueled, limiting cargo weight if needed, loading, etc....
It's hands on... flying is just ONE of your duties.
Yes, you do have support of a company, dispatch, and previous captains on the route, but it not JUST FLYING.
