>Thanks for responding Jon, Yes they are made by the same manufacturer. Hopefully the secondaries are color coded and I think they are. Not sure if thats a determining factor on phase to phase. I guess, the way to test would be, If it trips a breaker, it's backwards? Or there must be a better way to determine this?

Yes. Hook the primaries in parallel. Then, only hook TWO of the
secondary wires together, leave
the other pair apart. Measure the voltage between those other two wires
when you plug it
in. If it is just 1 or 2 volts, you can connect the wires. If it is
110 V, then the phasing is backwards.
Swap the wires on one of the transformers and repeat the test.
