Ed de Chazal commented: "I went down this road several months ago. I looked a little and found nothing. Doesn't mean there isn't one. I have a 60amp B&C alternator on my 360. After much discussion in this forum, I elected to install an 80 amp fuse on a 4 gage wire going to the alternator. The wire and fuse are well above the alternator output and if that fuse blows, the wisdom seems to be that you don't want to mess with the cause in flight. " I agree with Ed. Also my experience has confirmed that fuses are much more reliable than breakers and this is an area needing the best protection possible to prevent one cause of an engine fire. We must keep in mind that fuses are to protect the wiring from overheating due to current flow above their designed capability.
