30 AMP OPS
Hi again, Leroy.

We probably need to modify a few minor items.
Generically, the 50 amp male shore connection is
110-120v, not quite the same 220-240v as you likely
have in your home at your electric dryer and that is
typically why the male-female plugs for the dryer are
different from the ones you find in the Bird;
although, if the pedestal legs feeding the Bird are
out of phase with one another, 220-240V will be
present when measured from leg 1 to leg 2. (This "out
of phase" condition which results in 240V should not
be confused with "3-phase, 208V," although the
engineering concept is similar; 3-phase equipment,
mostly motors, must be specifically engineered to run
on three-phase current). Nevertheless, I am unaware
of any Birds 2004 or earlier that require, or use,
240V for appliances, although the generator will/does
produce it.

Your hypothetical #1, accomplishes what the normally
BB-provided 30A-male to 50A-female connector is
designed for, except it is internally wired to feed
both legs of 50A male and thus both legs of the main
panel, as long as no power is detected at the aux
connection. On many Birds, when power is detected at
the aux, one leg of the main panel will automatically
transfer to become powered solely by the aux feed,
while the other remains unchanged and fed thru the 50A
cord, however it is fed.
