The current draw of the motor control controllers is the load current plus some small quiescent current. I doubt that the OP would consider 30A per Victor a low-load application.

If the OP is running small motors that only draw a few amps in a non-FRC application, then selecting the fuses to protect the load is a valid way to go. From the photos, it looks like he is already using 14AWG or 12AWG wire which would be more than enough for a few amps.

The fuse holder Andrew linked to with resettable breakers would be a nice touch but the breakers might not be available in ratings that are low enough. The Blue Sea bus bars are nice too but the terminal blocks he is using would also be just fine. We use many of those in the equipment we build at work.

The fuse holder was chosen because I'm FAIRLY certain it will work with FRC style Snap-On resettable fuses. And those are available from 5-40A (though the holder is only rated for 30A per branch. I'll let you know if this is true on Friday when one is delivered.

I assumed the terminal block he's using was fine, I just linked the bus bar in case anyone was looking for something like it. (And I was hoping someone else would do a sanity check on if it would work for smaller than FRC applications)
