Personally I don't like contact breakers being used to protect the wiring to
avionics.
1) pilots can reset them easily and repeatedly then set fire to the wiring.
2) they wont act quickly enough to save the equipment in the event of an
overvoltage surge. (very common with some Rotax regulators),or save the
regulator in the event of a short.
BEWARE when installing equipment :hardly any american sourced avionic gear can
stand reversed or over voltage. Euro made gear is usually OK.
CBs are ok for motors, lights etc
IF fuses are used then you really should have a spare ONE of each neatly clipped
and obviously labled in the glove compartment or on the panel in case of
emergency .
