I am pulling a new 220V line from a power box for my new belt grinder
(20Amp 115/220V). Wiring is inside my garage and 8 gauge wires go
through conduit. San Francisco code requires 4 poles for 220V appliances
so I am using four wired inside conduit.
My question is how to wire switch and motor to four wires.
Motor wiring has 6 wires but instruction says that 3 wires go to one
pole and 3 other to another. What about ground and neutral?

Is there any good on line DIY manual for this kind of work.

4 poles would go to a dryer outlet, which has L1, L2, N, G

L1: first 220V line
L2: second 220V line
N: neutral -- voltage L1-N or L2-N is 120V
G: ground

I would never go to the expense of running 4 wires when you only need 3.
Nor do
I believe that San Francisco code actually requires it, but there are
amazing
things in California laws. Your motor will use L1, L2 and G, of course.

Although it might be a good idea to run the N for future consideration.
It can be left unused in the box.
