It obviously makes sense to have some circuitry protected by circuit breakers and some not-so-critical circuits protected by fuses. What have you done, and what - if anything - might you do differently if you were to start from scratch? Also, physical location of these fuses and circuit breakers has importance as well. Your thoughts? Thanks, Lance Goddard ________________________________ Message 2 _____________________________________ Time: 01:47:13 PM PST US From: "pilot623" Subject: RE: Pulsar-List: Fuses vs. Circuit Breakers I went with automotive type fuses all the way. The fuse blocks are mounted under the map/glove box, hinged to swing out from under the panel for access (but not in flight). I'd do it the same way again.

If they pop, doesn't that signify something, and what are you going to do ? Push them back in again - - why? On the otherhand, inexpensive automotive blade fuses serve the same purpose - - - they protect the wiring from some other malfunction. Mount them on inexpensive fuseblocks, accessible, but not while flying. If a fuse blows sort it out on the ground. Read some of the stuff written by Bob Nuckolls about wiring systems and fuses. I can sent a photo or two if you want. Brian XP, 912, 11 years and no fuse failures.

Each circuit has a light verifying the circuit and fuse. I carry color coded spares. So far no problems what so ever. Circuit breakers are expensive, and they are mechanical and can hang. They are reliable, but fuses are more reliable.

If they are labeled 10amp, they will do tha t indefinetely. Circuit breakers are a temperature device that are rated 8 0% of full load continuous. 90% will eventually trip. -----Original Message----- From: Dennis Adams Sent: Thu, Nov 10, 2011 5:51 pm Subject: Re: Pulsar-List: Fuses vs. Circuit Breakers Lance, We used fuses for each circuit, next to the rocker switch for the ircuit.
