Well, here is the answer from Blue Sea:

Dear Mr. Long,

Thank you for your inquiry. Unfortunately, the 5026 cannot be modified into
an individual terminal block. Our 5015 AGC fuse block can be modified in
this way, but it is only a 6-position block.

Best regards,

Scott McEniry
Inside Sales Manager
Blue Sea Systems

I guess I'm stuck with AGC fuses unless I can find a fuse block from a
different manufacturer. I need 12 fuses but so I'll probably put in two of
the 5015 units.
