I checked this, and rechecked this several times during the
operation. The plate specifies which strap to place on which
bushing for both parallel and series LV operation. On opening the
lid up an looking around carefully, I discovered that the straps
were stamped with letters that matched the designations on the
plate. This helped quite a bit, especially since I was not able
to use the same two bushings the plate specified due to the
difficulty of bending and re-routing the heavy straps in a wet
core.

I really could not expect much more for my $200.00, I am quite
happy with the results. Trust me, there are lots of arcs and
sparks to come yet.

I am going to post on this some more quite soon, if not today.

All the pigs I have looked at have copper HV windings, but I am
seeing a lot of pigs with aluminum LV windings. The copper wire
used for the HV winding on my 10 kVA 22890 volt pig is #14 solid,
the wire on the 25 kVA pig is either #12 or #10 braided (at least
connecting the winding to the base of the HV bushing beneath the
oil).
