-8- G1023S Series Heavy-Duty 10'' Table Saw
SECTION 3: CIRCUIT REQUIREMENTS
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
wiring 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, use a NEMA-style 6-15 plug
and outlet. See Figure 6. 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. Use a 15 amp circuit break-
er 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 current wires are
capable of handling a 15 amp load. If you are
unsure, consult the advice of a qualified electri-
cian. Do not attempt to modify an existing circuit
by replacing the circuit breaker with one rated for
a higher amperage.
110V Operation
The Model G1023S110 motor is prewired to oper-
ate at 110V. When operating at 110V, use a
NEMA-style 5-30 plug and outlet. See Figure 5.
Check the electrical codes in your area for
specifics on wiring requirements.
Under normal 110V use, the motor draws approx-
imately 24 amps. Use 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 cir-
cuit by replacing the circuit breaker with one rated
for a higher amperage.
