The Grizzly saw hookup originally asked about is a 3 wire hookup to
the electrical switch. Hot-Hot-Neutral. If the wire has a white
jacket on it, it is a neutral. Ground wires are bare.
Beyond that, if you open up your main service panel to your house,
there SHOULD be a little green screw run through one edge of the
NEUTRAL bar that connects to the back of the service panel, which in
turn is connected to the GROUND bar in the service panel. That said
in the main service panel there is a completed circuit between neutral
and ground in a 4 wire hookup. In sub-panels, the "green screw" is
removed and the 4 wires (hot-hot-neutral-ground) are run separately to
the main service panel. It's just a formality done so that an
electrician can tell it is a sub panel, since back at the main panel
the ground and neutral are combined...see above. This is according to
current NEC code.
So, the whole neutral or ground argument is mute...they connect
together back at the panel. Therefore, if it's got a white jacket,
call it neutral, if it's bare, call it a ground.

A 20 amp two pole breaker is worth about 15 bucks. Although I agree in
principle that the system will run fine on the 30 amp circuit, I wonder
whether your warranty would still hold if something happened. The internal
wiring and switches on their machine will not be of adequate gauge for 30
amps of current, so if a wiring fault occurs in the saw, the risks may be
higher. Sure, Grizz should have designed the system to internally trip with
excess current. Also, the resistance and design of the motor should
automatically limit the amperage of the circuit. However, suppose that you
started a fire caused by excessive current, and your house burned down.
Would Grizz be expected to pay? In the owner's manual they say that they
want a 20 amp circuit, period. I suspect they don't say 'minimum 20 amp
circuit'. So their lawyers could argue that you made a mistake. If you blow
the motor and Grizz find out that 30 amps were running through the wires,
they might find cause to contest your claim. Changing the breaker is a
one-minute job, and you can then say that you followed the owner's manual to
the letter. You can always change the breaker back to 30 amp later, if you
wired it as a 30 amp circuit.
Cheap insurance.
As I said befo
Please. You should refrain from offering electrical advice. I'm sorry
if that hurts your feelings, but your reply does not reflect the
slightest bit of reality with regard to electrical theory,
engineering, or legal requirements.
