Re: UDR56K-4 current draw / fuse

David's points are part of the reason that engineering chose to go with the RAST 5 solution.   For those who use Anderson Pole connectors, the other end of the 2 meter cable can be mated with Anderson Pole connectors or any other type chosen by the owner. 

As a side note: Utah amateurs where some of the first to adopt Anderson Pole connectors. Later they were adopted by a number of ARES/RACES groups as a 'standard' -- however, the left-hand/right-hand orientation of the positive and negative terminals were reversed from the Utah 'standard'.  Hams in Utah relented and adopted the same orientation as other groups.

Powerpoles add cost & unpredictability.

They are not waterproof (an odd choice for emcomm), they must
be assembled carefully or are prone to failure, they tarnish
over time and only partially self-clean during connect-disconnect
cycles (when tarnished they demonstrate high-loss for low current
and high current demands), and the most common connectors are
unsuitable for high current apps (requiring a higher amp-rated
non-interconnectable version of the PP 75a vs 35a). They are
also easily bumped loose, creating intermittent connections, or
completely apart.

I removed all of them and went back to sure-connect bare wire
and crimped wire connectors (they are cheap, simple, available
everywhere) and terminals. Reliable & simple.

Most users almost never, if ever, interconnect with anyone nor
do they frequently connect and disconnect most of their gear -
once set up.

IMHO, YMMV ...
