220V Operation
The motor supplied with the Model G1023S110
can be operated at either 110V or 220V. The
motor comes prewired for 110V. Refer to the wir-
ing diagram insert supplied with this manual for
information about converting to operate at 220V.
If converting to operate at 220V, a suitable 220V
plug and magnetic switch must be wired in.
When operating at 220V, we recommend using
a NEMA-style 6-15 plug and outlet. See
Figure
5B. 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 require-
ments. You will also need to replace the existing
110V switch with a magnetic 220V switch such as
the Grizzly Model G4572.
Under normal use, the motor draws approximate-
ly 12 amps at 220V. We recommend a 15 amp
circuit breaker for 220V operation This should
be satisfactory for normal use while providing
enough protection against circuit damage caused
by power surges. Always check to see if your cur-
rent wires are capable of handling a 15 amp load.
If you are unsure, consult the advice of a qualified
electrician. Do not attempt to modify an existing
circuit by replacing the circuit breaker with one
rated for a higher amperage.
SECTION 2: CIRCUIT REQUIREMENTS
110V Operation
Model G1023S110 Only:
The Model G1023S110 motor is prewired to
operate at 110V. When operating at 110V, we
recommend using a NEMA-style 5-30 plug and
outlet. See
Figure 5A. 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 specif-
ics on wiring requirements.
Under normal 110V use, the motor draws approxi-
mately 24 amps. We recommend a 30 amp circuit
breaker or a 30 amp slow-blow fuse.
The circuit you use should be dedicated, (i.e., the
Model G1023S110 should provide the only draw
from that circuit). If frequent circuit failures occur
when using this machine, contact our Service
Department or your local electrical contractor.
Because of the high amperage draw of this
machine when wired for 110V, standard house-
hold circuit wiring may not be of a large enough
gauge. A qualified electrician must install a new
circuit with wires capable of handling a 30 amper-
age draw. Do not attempt to modify an existing
circuit by replacing the circuit breaker with one
rated for a higher amperage.
