In reading several posts, I've noticed that most builders seem to prefer fuses rather than circuit breakers. Can someone tell me the advantages of one over the other?
Thanks,

For a typical RV, fuse blocks are cheaper, easier to install, easily
provides individual fuses per device that require power, and the fuse block
itself does double duty as a buss. In other words, each radio, GPS etc gets
its own fuse. You will still need a few dedicated breakers for things such
as Alternator and things you may want to reset once in flight. Such as flap
motors which may trip due to over current due to heavy load because you
selected flaps down at too high an airspeed. Known causes of trips like
these may be candidates for ONE TIME in flight reset. Some people put the
autopilot on a pullable breaker so that it can be shut down in flight.
There may be other reasons for breakers but many like to go with fuses.
