Don Gordon asks about availability of a 60amp circuit breaker for the
alternator....

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.    Earl
