Breaker sizing (Amps) in breaker panel

[a64pilot]

I understand the logic of sub panels, or individual fuses, but I like "homerun" circuits.
Of course this has caused me to install another 8 circuit breaker panel.
I hate fuses, this I think comes from being a pilot. In flight resetting a circuit breaker usually isn't a big deal, but changing a fuse can be.
I really dislike in line "hidden" fuses. Whenever I install something with an inline fuse, I put a zip tie on it with the hope five years form now trying to figure out why all of the sudden the VHF doesn't work, I'll see that zip tie and think, check the fuse.
I'm getting forgetful, the other day I was looking at a wire that ran though the engine compt. I knew I had put it there, but I had no idea what it's function was.
I guess a schematic wouldn't be a bad idea

I agree about hidden fuses. As I posted earlier - I put these on light fixtures when I upgraded to LEDs. These fixtures came with 22ga pigtails - I was uncomfortable attaching these to a 15 amp breaker..

On my boat any fuse is only attached to one device - and is local to that device (Nav system excluded on that - used sub-panel there). I feel this strategy makes maintenance simpler.

Tags on fused lines or a schematic sounds like good practice - especially for a new owner or partner who works on system too.

I hate hidden fuses.

AS a a young marine tech I started to pull out the wiring leading to a VHF that would power on the bench but not in the boat. Despite there being a fuse panel with in 2' of the VHF with a VHF fuse in it there was also an inline fuse behind a trim panel between the two. Very annoying.

Recently I was on a 55' motor yacht less then 10 years old. It had multiple DC breaker panels and fuse panels, despite this there were still a half dozen unlabeled in line fuses in the engine room from the factory.

Redundant in-line fuses are simply cruel. Any in-line fuse should be local to device and visible...

On a reno project - i discovered a circuit with a pair of series wired GFI outlets at opposite sides of a house.... That one took a few hours to ring out.

Problem remains - breaker has to protect all wiring on the circuit. Fans and lamps are notorious for undersized pigtails.
