Yeah . . . you noticed too. Suggest you just
ignore the die-size labels.
The short story is to first select a terminal that
is SNUG on your wire strands. If your nearest
best choice is not snug, 'stuff' it with copper
wedges as described in the article on soldering
terminals on FAT wires. Minimizing voids
in the wire grip is critical to success.
Then select a die set that comes to within an
1/8th inch or so of closing. Do the mash.
Do some test crimps (terminals are cheap off
eBay et. als.) Put the terminal in a vice
and pull on the wire. You should not be able
to dislodge it. If you can, repeat with the
original die selection and then add-a-crimp
with the next size down.
The 'too small' die may generate some squish
out at the sides of the wire grip barrel . . .
but it will insure the quality of your grip.
It's okay to sand or file off these little
'wings' of upset copper.
Apply the obligatory double-wall heat shrink
and you're good to go.
I've done about a half dozen test crimps with
the tool I have. I've built a couple of heavy
duty jumper cable sets. By the way, good
cables with #2 or larger wire are pricey . . .
but I found that unit cost can be mitigated
by purchasing a 20 or 25 foot set, cut it in
half and add two sets of clamps to end up with
two 12 foot cables.
I plan to do some more experiments and perhaps
do an article for Kit Planes on the technique.
The finer granularity of sizes is what makes
these latest offerings play well. Ignore the
labels. Optimize occupation of the volume
in the wire grip, eyeball the first-try
die selection, you can always hit it again
with a smaller one, then play tug-o-war with
your experiment.

out of that stuff?"

Since you guys have bullied me into using fuses:) , I'm looking at installation
ideas. I actually see some other benefits other than those mentioned.
The RV14 has an area in the fwd area of the center tunnel that most builders
use. Vans even has a kit that fits this area to allow the fuse/cb panel to
be angled so it is more accessible and easier to view. Also gives more space
behind the fuse/cb panel for wiring.
I will attempt to post a couple of pictures to show what I'm considering.
Also, I attached a link to a fuse block I found during initial research.
Sorry, pictures look like they are very large. I will try and re-size when I
a minute. T
As always, all critiques and ideas welcome.

[quote="Mudfly"]Small changes to the Primary Power System diagram.
Also added interconnect drawing for STBY Batteries.
Updated drawings attached.(UPDATE 2/7/22 -REMOVED INTERCONNECT DRAWING FOR STBY
BATTERIES -- AFTER CONSULTING TCW, I WAS
ADVISED MY DIAGRAM WAS WIRED INCORRECTLY) Back to the drawing
board for that system.[/quote]
