Electrical fuses

In accordance with CAT.A.110, airplanes shall be equipped with spare electrical fuses, of the ratings required for complete circuit protection, for replacement of those fuses that are allowed to be replaced in flight. However I have not found electrical fuses in 737 WDM, correct me if I am wrong.......

If memory (doesn't) serves me.... I remember the fuse below used on 727's for generator output protection. These were high amperage, around 250 amps.
  
     
  
I've seen similar on corporate aircraft. I've also seen the standard replaceable fuses on corporate aircraft.
  
     
  
Airbus aircraft (at least the A300-600) have replaceable fuses for panel background lighting.

I looked at the 737-400 wiring manual..... I couldn't find any used on that aircraft type.

Which document has to be consulted to identify avionic parts which are allowed to be replaced in flight?
