Grizzly G1140 Circuit Requirements, 220V/110V Operation, Circuit Load, Grounding

SECTION 2: CIRCUIT REQUIREMENTS

220V/110V Operation

The Model G1140 has a dual-voltage 11⁄2 HP, 1720 RPM motor which has been pre-wired for use in a 220V single phase circuit. The cord set enclosed does not have a plug as the style of plug you require will depend upon the type of service you currently have or plan to install. If you will be installing a new receptacle and plug, we recommend either of the styles shown in Figure 1. Note that you have the choice between simple plug-in and twist-lock plug styles.

Should you prefer to utilize the 110V capability, a wiring diagram is provided near the back of this manual showing the wiring changes needed. Operating at 110V will also require installing a grounded plug.

Circuit Load

The Model G1140 will draw approximately 8 amps at 220V and 16 amps at 110V. Circuit pro- tection when operating at 220V should be on a breaker rated at 15 amps or a fuse rated at 20 amps. At 110V a 20 amp slow-blow fuse or breaker should be used. Fusing at amperage rat- ings higher than these will not adequately protect the motor from high heat caused by overloading. 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.

Be aware that other machines operating on the same circuit simultaneously will also add load which can cause the circuit protection system to trip.

Grounding

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 is equipped with an electric cord having an equipment-grounding conductor which must be properly connected to a grounding plug. The plug must be inserted into a matching outlet that is properly installed and grounded in accor- dance with all local codes and ordinances.

Improper connections of the electrical-grounding conductor can result in risk of electric shock. The conductor with green or green and yellow striped insulation is the electrical-grounding conductor. If repair or replacement of the electric cord or plug is necessary, do not connect the equipment grounding conductor to a live terminal.

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 injury may occur.
