Here is a simplified block,
with ~ representing the wall AC,
f1-3 representing the fuses,
and r1-3 representing the loads of each power supply.

I am assuming this statement is true:
The configuration shown is the same as if I had 3 x individual devices
on the same power strip,
or 3 devices in one box with the input AC split 3 ways.
If this is true, then it would mean that if I had the 3 individual
devices with the
correct fuse and put them all on the same power strip and turned them
on at
the same time, then each of the fuses would blow, even though if turned
on
one by one, each would work correctly. ??
Is this because:
a) f1-3 are just wire, and in effect the same point?
b) the transformers have a spike upon power-on that somehow their
neighbors "see"?
What transformers? You didn't indicate any transformers.
For that matter, you didn't indicate what the loads were
*really*. I get the impression that r1, r2, and r3 aren't
simply resistive loads.
