Richard,
If I were you I'd buy a second 7200-240/120 pig. That way
your original investment is'nt wasted. Unless of course you
can trade your old pig in. Second, I'd rewirer your LV back to the
Delta configuration and wire the pigs together for parrelel
operation (While your HV are in series). This is my opinion,
I like keeping things simple.
Last, who do you know that sells 14,400 10 KVA pigs?
I'd like to have thier phone number.
