With due respect, what William meant to say is that, against the anti-CB tendency of you and many people in this forum, he has found a particular circuit (the "cigar" lighter-type power port) where a circuit breaker is the preferred method (instead of a fuse) |
No argument . . . Cessna went away
from a 20A inline fuse to a 10A breaker
no doubt 'cause folks were popping the
fuse a lot.
The point being offered is that a well
considered array of loads to one's airplane
will never nuisance pop a breaker or fuse.
Knowing loads and limitations before
'hooking up' is a good thing to do . . .

Interesting! This is a 14 or 28v airplane? Check
your maintenance manual for the factory installed
part data . . . the drawing I posted was for
a group of 172's.
Given that all the single engine products were wired
by one electrical group, features in one model tended
to ripple across the spectrum of products . . . but
that's not a hard/fast rule. If you don't have a manual,
give me the s/n of the airplane and I'll see if my
'contacts' can shoot us the drawing.

The plane is a 1956/57 14V 172, its serial # is 29628 which is supposed to by 1957, but it has some 1956 features like fuel vent on top of the wing. In the years since 1957 someone had replaced the ‘cigar’ lighter fuse with a 5A circuit breaker, which with a 14v plane is not very many watts. I have the original parts catalogs, but cannot find fuse information in it, and back then the regular manuals were very limited in detail.
