VIII. ELECTRICAL SERVICE REQUIREMENTS
The Grizzly Model G1024 Shaper is furnished with a complete electrical package: A 3450 RPM
TEFC
3
/4 H.P. motor, ON-OFF starter switch, FORWARD/REVERSE switch and a cord set. The
motor is single phase and may be operated on 220/240V, as well as 110/120V.
A. GENERAL
The Model G1024 comes with a standard 110V cord and plug. Its motor draws 10 amps. While that
is not excessive, using the Model G1024 on a circuit that is already close to capacity could result in
overload. If possible, add a circuit specifically for the shaper. A 15-amp circuit breaker is ideal for the
Model G1024.
If you choose to re-wire the Model G1024 for 220V operation, use NEMA-approved connecter plugs.
See Figure 2 for examples of typical plug configurations. You should also check with our service
department for specific information on motor re-wiring requirements. Your local building department
or a licensed electrical contractor should also be able to help you if electrical requirements exceed
your understanding.

If you are plugging into an existing outlet, ensure that it is grounded. If not, it will be necessary to
run a separate grounding wire, #10 copper or larger, from the frame of the machine to the ground-
ing stud at your service panel.
If you find it necessary to use an extension cord with your shaper, make sure its conductors are rated
at #10 or larger (for 220V). The cord should be rated for hard service (S-type jacket), with NEMA-
approved connectors and a ground wire. An SJ-rated cord (#12-wire) should be sufficient for 110V.
CAUTION: Never cut the grounding pin from the plug. If you have problems with the electrics sup-
plied with the G1024, please contact our service department for assistance. Should you decide to
use a larger motor on the machine, DO NOT rely on the information above. Contact a licensed elec-
trician or your local building department for proper wiring requirements.
