Be carefull doing this. All foreign 240 mains that I have worked with have
been 240 between hot and neutral. This works out to be 416 phase to phase
on 3 phase systems. What you will be doing is 240 between 2 hots. This
can and will cause problems with a lot of supplies that expect the neutral
to be at / near ground. I have several isolation transformers that I use
for all the UK equipment I service and they all are wired for 240 Hot to
neutral output.

Also be careful what electrician you get to set it up for you. I have seen
plenty of them manage to wire them wrong. I have even had to explain to
them how to wire a buck / boost transformer only to have them fuse it for
isolation ratings.
