1) Don't use multiple small breakers for each item. Rather use one
large single master breaker (like a 5A or larger) as you can probably
afford to loose that 0.25Vdc.


The downside to a single large device is that if you have a short in
wiring to one component (it's not likely to be a failure within the
device) then with #1 above you have now lost power to ALL your instruments.

I would suggest that a single large device SHOULD be mounted directly on
the battery, (preferably right next to the negative termanal) but it
should have a high interrupt load - 10 amps or even more. If you have a
short in the wiring between the battery and the rest of the panel, this
will keep a short from making a mess (possibly behind the seatback or
even under the seat). If you do have a short, a 10 amp fuse will open
very quickly.

Meanwhile, back to the original request. SH is outfitting new gliders
with these neat little "resettable fuses". I'm still curious if anyone
has seen something similar in the US???
