Be carefull doing this. All foreign 240 mains that I
have worked with
have
been 240 between hot and neutral.
Ours certainly are.
This works out to be 416 phase to phase on 3 phase
systems.
About right, the standard says 415v but that's close enough. I doubt you'd
feel the difference :^)
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.
This is perilous at best. I'd be tempted to find a better way..
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.
Same here.
