TYPE: The automotive flat inline-blade type seem to be best [RigRunner
uses them]. Very large [relative to other designs] contact area, very
strong wiping-action on insertion and removal. Not gas-tight, I pull
and reinsert mine every now and then, when I think about it.
RATING: Since we're fusing the primary power, I think the old ROT [rule
of thumb] has been 125-150% of the likely normal maximum load current.
That of course depends on the configuration of the K3. My K3/100 has
been fused at 25A for years. That's close to 150% of key-down.

I hoping to buy a 100W version of the K3 next year. I note recommendation
that the rig be fused on both sides of the 12 V supply line. What is the
recommended fuse type and rating for this application?
