The hot wires from the two 30 amp connectors (one per connector) will
go to the two hot wires on the 50 amp connector. From the description
in the West Marine catalog, it appears the adaptor has some "smarts"
in it to prevent damage from incorrectly wired outlets on the dock,
and to prevent the prongs on an unplugged 30 amp plug from becomming
hot.

You can still only draw 30 amps from each 30 amp dockside outlet, for
a total of 60 amps at 120 V - but you can only use the full 60 amps if
your wiring on board splits the loads evenly between the two hot wires
in the 50 amp cord.
