Dan,

Richard is in Australia, with a 240 single phase MEN system.
This set up sounds like you were thinking of the 120/120V CT system used in
the US.

As long as the phasing is correct, you can stack quite a few of them.
However, if you are stacking a large number of them, its better to run
them
off 240VAC as if you were running 120VAC for the full stack
the current can get quite high.  To run off 240VAC, you will need an
even
number of them.  Simple wire the outputs all in parallel (watch for
proper
phasing), and then series each pair of NSTs inputs together and run off
240VAC.  That will give you about 120VAC per NST for each series'd pair.
Again, watch proper phasing.
