If it is 4HP there is a very STRONG chance it can be re-jumpered for
240 volts. I had the same problem with my compressor - 240 fixed it.

He is *already* running at 230 VAC which is just another way of
saying 240 VAC these days. Normal outlet voltage has been changing over
the years. I remember some equipment rated at 110 V, then 115 V, then
117 V, and now 120 V. 230/240 is simply double whichever voltage is the
current one.

And 14.5 A is pretty high for an outlet-connected motor, and
would be certain to pop a 15A breaker. If the wiring is heavy-duty, he
may have 20A braker and outlets. But a motor rated breaker, with the
curve which allows longer/higher start-up currents while working at the
normal current for really long-term power drains..

Enjoy,

I missed the 230 volt reference - What amperage circuit is he on???
Virtually never see 15 amp 240 around here - very occaisionally see
20, more commonly 30.
