Is it possible to purchase and install (legal, not technical) a 3KVA 240V
3-phase convertor in a residence for powering WW machinery? Is there
something in the zoning laws that would prohibit this?
The reason I'm asking is that I will be bringing back my stationary machines
from Europe which are all wired as 240V. I'd like to evaluate whether it's
better to re-equip the machines with 220V single phase motors of comparible
size or simulate the correct supply for the installed motors. Since I'm a
single operator, the convertor would be sized for the largest motor (because
I will never operate more than one machine at a time).
The stationary machines -- bandsaw, tablesaw and planer/thicknesser -- have
3 phase motors wired in 240V, 50 Hz delta with ground, no neutral. It is
possible to easily rewire the motors for 240V star with neutral and ground.
I also own several portable tools -- biscuit jointer, Skil saw, sander,
router -- with single phase 240V 50Hz universal motors that probably will
work off of 220V 60Hz single phase but may benefit from running off one
phase of the convertor if possible.
Technically, there is some sort of solution but my question aimed more at
the legal requirements imposed by some planning board which might view such
a convertor as industrial equipment and prohibit its use. For example, it
may require installing a special 220V feed from the distribution panel
requiring planning permission. I don't know.

Be aware that voltage is not the problem. Canadian voltage is 240 volts,
ranging from 230 up to 250 volts. Your problem will, of course, be if you
need 3 phase, and even more important Canadian frequency is 60 cycle vs.
European 50 cycle. This can cause problems. You may be better off buying new
motors.

Robert not clear if your European Motors are 240v 1Ph or 3Ph? If Single
Phase then most Motors are Rated at Stated Voltage on Motor Plate plus/minus
10% and therefore will work satisfactorily at 220v

there's a chance they're 50 hz. motors.
