I bought a Grizzly G1022Z table saw almost two years ago. I have been
running it on 120v, on GFCI outlets with no issues. My new shop has
several 220v outlets so I decided to reconfigure the saw for 220v.

After rewiring the leads from the motor, as per Grizzly's wiring
diagram. I decided to test the new configuration for ground.

There was no continuity between the ground prong on the saws plug and
the frame of the saw.

When I check the ground lead from the plug into the saws switch,
there was continuity. But the two ground conductors in the switch were
not connected to each other or to a common ground in any form or
fashion.

Grizzly had connected the two ground leads, one from the plug and one
from the motor to the screws that hold the switches cover plate in
place. Both of these connections are totally isolated from the frame
or from each other.

When running a 120v system on a GFCI, the system will run without a
ground and the GFCI should provide a considerable amount of protection
from electrical faults. Still, I can see no reason to not have a
functional ground.

When running a 220v system that is not on a GFCI, you really need a
good ground.

Has anyone else had this issue with Grizzly tools? I guess that I'm
going to have to test every Grizzly tool in the shop to see if it is
wired correctly.
