How do I wire up a 480v Single Phase circuit? I'm familiar with 480V
3P but not single. The machine has a preinstalled 3-wire cord, one
of
which is a ground so I'd only be using twom wires.

Also what exactly does poles mean? Like a circuit breaker is either
1-2-3 poles, is that the same as phase? Thanks.

480 volt single phase motors / equipment is very rare to say the
least.
There is
only one i know of and it is the 480 volt HVAC rooftop systems which
have
480
volt condenser fan motors on them. First you have to get 480 volt
service
to the
building which only comes in 3 phase service and just use two of the
hots
of the
3 hots for power. If your thinking of running this at your house. the
cost
is
going to be high to get 480 volt service to your house. The electric
company
will supply you with 480 volt service for about $4K atleast and then
you
have to
be set up to have the switch box for the 480 volt serice.

Now you can look into getting a buck and boost transformer and get 480
volt
service out of your home 220 volt service. That will run you about $2K
atleast.

You got me here with what you would have that runs on single phase 480
volt that
could be useful to you. It would be nice to know what it is.


Hello, Turtle.

You gots me there too--mebbe he found some lights for cheap and is gonna
grow dope or something.....

Now for a small load, a transformer for 220/440 shouldnt be too
expensive on
the surplus market though--Ebay, perhaps.....

I have very seldom that a small load on something that uses 480 volts to
pull
it. You use 480 volt service to get it on for power of anything using it.
other
than that 220 volt service will run a great deal and easler to find power
for
it.

Awwwwww E-bay for quality stuff. Not Me.


Okay--agreed......

Still he leaves me to wondering what exactly is it he is trying to fire up
here ???

I have transformers do this 220/440 and vice versa but alway for 3 phase
stuff.
