VIII. ELECTRICAL SERVICE REQUIREMENTS

The Model G1126 is furnished with a complete electrical package: A 1,720 RPM 11/2 H.P. motor, ON- OFF starter switch, FORWARD/REVERSE switch and a cord set. The motor is single phase and can be wired for 110V or 220V. As delivered, the G1126 is ready for 110V operation. If you want 220V operation, the wiring system must be changed for the desired voltage.

A. GENERAL

The Model G1126 comes with a standard 110V cord and plug. Under extreme load, the Model G1126’s motor could draw a potential 22 amps. Yet under the majority of circumstances, the Model G1126 should work satisfactorily when connected to its own dedicated 20-amp circuit.

If you choose to re-wire the Model G1126 for 220V operation, use NEMA-approved connecter plugs. See Figure 1 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 require- ments exceed your understanding.

B. GROUNDING

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 grounding stud at your service panel.

If you find it necessary to use an extension cord with the Model G1126, 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 electrical equip- ment supplied with the Model G1126, please contact our service department for assistance.
