what to put on circuit breakers

[Greenley]

Building an RV10 with Garmin G3x touch, full autopilot including yaw, GTN650 and a second radio. Trying to look at what to put on my circuit breaker panel, and what to put on an inflight accessible fuse panel, but not nearly as accessible as the visible circuit breakers. Not using Vertical Power. Primary and backup B & C alternators, and wiring for PMags, but will probably be using shower of sparks to start off with.

Is this a reasonable split between breakers and fuses, suggestions?
Thanks,
Bill

My current thoughts are:

I did a similar split for some items, partly because I ran out of fuse slots and sub-panel space but also for things like P-Mags, that should have a physical disconnect when charging the battery.

For some, I wanted to *know* if there was a short (can't see the fuse easily) and some because they were needed after the fuse slots were all used up.

* P-Mags (easy disconnect)
* Flaps (want to see it)
* Fuel pump (want to see it)
* Alt Field (want to see it)
* Alt Fail (out of fuse slots)
* Auto pilot servos (AP gone wild/easy disconnect)

EDIT: I would have had one for trim servos but installed the Dynon AP panel, which provides similar safety measures.

Bill,

A few thoughts:
- If you are using the two axis Safety Trim or similar, one breaker for both pitch and roll trim.
- I'm a fan of Switch Breakers instead of a switch with a breaker or fuse. Here is example: http://www.aircraftspruce.com/catalo...rcuitbrkr2.php You end up with one hole in the panel instead of two. Applications include fuel pump, pitot heat, landing lights, strobe lights, nav lights, Alt field. I know some people don't like these but I have been using them for 14 years without a failure.

I personally prefer Klixon and Honeywell as the Tyco quality issues have been known for quite some time.
