Hey guys,

I was looking at getting a KILN that requires 220 3-phase (31amps) to
run. Does anyone know what HP rotary phase converter I'd need to run
it?

Thanks!

Hey James,

Welcome back. Merry Christmas. Drop in more often.

220 VAC at 31 amps works out to 6820 watts. Using a loose rule of
thumb, it takes 750 watts per horse power. Therefore, your kiln is
equivalent to a 9 HP motor, and rotary converters are derated by as
much as 50%, so you would need a 15HP 220VAC 3-phase motor set up as
the rotary convert or to accommodate it, IF it was a motor. But it's
not. I suspect that there are also reasons other than the heaters
that this is three-phase. So, best advice was given by another......
Try contacting the manufacturer, and if they can't tell you, ask for a
schematic, and get back to us.

Take care.
