According to Ignoramus27577 <ignoramus27577@xxxxxxxxxxxxxxxxxxxx>:
This Quincy compressor that I won is connected through a wall mounted
mag starter switch. The built in regulator switches the contactor
coil. It's all pretty normal.

Except that you don't *want* the contactor, if you are going to
run this from a VFD (which is what you said earlier). Granted, someone
with power company three phase -- or even a rotary converter of
sufficient size -- might what the starter.

That, or I can use or sell it myself.

But with a VFD -- there should not be switching between the
VFD and the motor. Instead, you modify the control signals to tell the
VFD to start and stop the motor -- and you can reduce starting current
by doing this.

Correct.

As for the legality of removing the mag starter? I guess that
this hangs on whether the Quincy was sold *with* the starter, or whether
it was separately purchased and installed.

I will post an update after I go there. Thanks to all.
