Has anyone provided redundant power sources for their EC2?
  Currently I have power supplied via a circuit breaker, but I'm
considering adding another power supply wire fed with a fuse.
However they would both still feed through pins 33 & 34 which are
internally connected. So even if I was to separate these pins for there own
feed (they are currently fed from the same wire), a short on either one
would likely cause both the fuse and CB to blow.
   I'm just trying to take care of a last few things on my list before
taking this plane up to the airport and something I'd added to the list
many years ago was redundant power for the EC2 since a failure of that
could really ruin my day.
    Since the most likely point of failure (even though it's quite
unlikely) would be the DB37 pin connector on the EC2, I'm not sure that it
is worth the effort to open up the connector shell to add another power
wire.
  I've changed my mind on this several times over the last while and now
I'm running low on time so I'd throw it out for the collective wisdom of
the group.
