I run all my 12v equipment (almost anyway) on a 50A Astron PS. Since
the PS is rack-mounted in a half-height cabinet the dc cable is about
12-foot long, so I used #4 welding cable that terminates on a 30A
Fuse holder. That feeds two HD barrier strip terminal blocks (for
pos and neg rails). The terminals accommodate No. 10 awg cables to
the heaviest current loads. A secondary strip handles small stuff
(under 5A total).
The PS runs 13.71v and drops to 13.5v at the fuse holder. K3 sees
about 13.35v (radio is 10w version). I have only two PowerPole
equipped pieces; the rest use terminals or other connectors like
Molex, etc. (even one Cinch-Jones). I count 14 loads connected to
the 13v power distribution (not all are used simultaneously).
In the case of running to a regular-sized PP connector I just add a
few inches of no.14 awg (splice is two wires soldered and covered
with heat shrink)
