Fuse box puzzle

I’m concerned about the wiring above fuse #2 & #3 in the sub. Any input?
Fuse #3 (30 Amp) has 12 gauge wire as well as all the 30 Amp fuses in the main which has 60 Amp service.
In addition the mast is not visible and looks like it never has been. Service wires are too low above the patio roofing and touching the building along with tree branches toward the service pole.
