I have a Grizzly G0444Z table saw and a G1029Z dust collector. Both run on
220. The saw cord has a green wire which is ground and a red and black which
are both hot and the dust collector cord has the same. Both draw 15 to 20
amps. I have 12/2 with ground
romex cable (white, black and bare ground wires). I was told by Grizzly to
use a 20 amp/220 double breakers on both and 12/2WG and color the white wire
as black or red. I think they said each motor has capacitors, what ever that
means. What confuses me is in the past when I wired a 220 circuit I always
used 12/3WG ( red, black, and white with a bare ground wire). Have any of
you wired your saw or other machinery like Grizzly told me to? In addition
to grounding my dust collector vacuum lines I was thinking that I would go a
head and run a ground wire on each unit to the cold water pipe for added
protection. I would appreciate any advice you could offer me. Thanks a lot.



If you were using conduit and seperate conductors, you would use 3
wires: black, red (or a 2nd black) and green (or bare). Since you are
using a 12/2 cable, you can use the white wire for one of the "hot"
conductors if you wrap black, red, or blue tape around the ends of the
insulation or paint with some red nail polish.

The ground wire in the cable should be adequate; don't mess with the
water pipes.

If you are using plastic pipe for the vacuum lines, run a bare wire (it
doesn't matter what size) inside the lines from end-to-end and ground to
the metal housing somewhere to dissipate static.

HTH :-)
