I'm getting a workshop built, and can make a choice to have 3 phase

I'd like to buy some ex-factory machinery.
Q: Is it worth the expense? Or, with electronic solutions to running 3
ph. machines from single phase power, is it not worthwhile?


Hey Jordan,

You don't give much detail about what you are doing. If for instance
this is to be a private workshop on a residential property, the
utility company may well be happy to provide a three phase (440???)
service, which gets you power at industrial rates, and you can run
your shop AND your house from it. You will have to buy a transformer
for it to get the 110/220 household requirement, but in so doing you
will then have a service suitable for all needs, eg single phase 110 &
220, and 3 phase 220 & 440. Good deal I think.

Ask to speak with a technical representative at your utility. They
can be very helpful.

Tale care.
