SECTION 2: CIRCUIT REQUIREMENTS

110V Operation

 

Grounding

 

 

 

 

 

 

The motor supplied with the G1004/G1008 is a dual-voltage 110/120V or 220/240V motor. (For information on operating at 220V, see the section following entitled 220V Operation.) Under normal use, the motor draws approximately 16 amps @ 110V, therefore it should be connected to a circuit that is protected by a 20 amp fuse or circuit breaker. This should be satisfactory for normal use, while providing enough protection against motor damage caused by power surges. Grizzly recommends that the circuit you use should be dedicated, (i.e., the G1004 or G1008 should provide the only draw from that circuit). If frequent circuit failures occur when using the milling machine, contact our service department or your local electrical contractor. You are cautioned that equipment returned to us for service that shows evidence of being over-fused will be repaired or replaced totally at the customer’s expense, regardless of the present warranty status.

It is also necessary to connect a cord and plug to the machine. Be sure that both the plug and cord are rated at 20 amps and must include a grounding wire. See Figure 1.

In the event of a malfunction or breakdown, grounding provides a path of least resistance for electric current to reduce the risk of electric shock. This tool must be equipped with an electric cord having an equipment-grounding conductor which must be properly connected to a grounding plug. The plug must be plugged into a matching outlet that is properly installed and grounded in accordance with all local codes and ordinances.

Extension Cords

If you find it necessary to use an extension cord with the Model G1004/G1008, make sure the - cord is rated Hard Service (grade S) or better. Refer to the chart in the standard safety instructions to determine the minimum gauge for the extension cord.

The extension cord must also contain a ground wire and plug pin. Always repair or replace extension cords when they become worn.

Potential for electrical shock hazard, this equipment must be grounded. Verify that any existing electrical outlet and circuit you intend to plug into is actually grounded. If it is not, it will be necessary to run a separate 12 A.W.G. copper grounding wire from the outlet to a known ground. Under no circumstances should the grounding pin from any three- pronged plug be removed. Serious personal injury may occur.
