G8793 12" Double Disc Sander -5-
220V Operation
The motor supplied with the G8793 can be oper-
ated at either 110V or 220V. The motor comes
pre wired for 110V. Refer to the wiring diagram
inside the motor cover for information about con-
verting to operate at 220V.
If converting to operate at 220V, a suitable 220V
plug must be wired in. When operating at 220V,
we recommend using a NEMA-style 6L-15 plug
and outlet. See Figure 2. You may also “hard-
wire” the machine directly to your panel, provided
you place a disconnect switch near the machine.
Check the electrical codes in your area for
specifics on wiring requirements.
Under normal use, the motor draws approximate-
ly 10 amps @ 220V. We recommend a 15 amp
circuit breaker for 220V operation This should be
satisfactory for normal use while providing
enough protection against motor damage caused
by power surges.
SECTION 2: CIRCUIT REQUIREMENTS
110V Operation
The G8793 Sander motor is prewired to operate
at 110V. A 110V plug is included with this
machine. The plug must be used in a grounded
receptacle similar to that shown in Figure 1.
Under normal 110V use, the motor draws approx-
imately 20 amps. We recommend a 20 amp cir-
cuit breaker or a 20 amp slow-blow fuse.
Grizzly recommends that the circuit you use
should be dedicated, (i.e., the G8793 should pro-
vide the only draw from that circuit). If frequent
circuit failures occur when using this machine,
contact our Service Department or your local
electrical contractor.
