Grizzly G2790 Circuit Requirements, 110V Operation Grounding, Fusing, Extension Cords

SECTION 2: CIRCUIT REQUIREMENTS

110V Operation Grounding

The Model G2790 is wired for 110/120V, single phase operation only. The 1/2 HP, 1720 RPM motor draws 8 amps. This is not a large load. However, if you operate the grinder on a circuit that is already close to capacity, it could overload that circuit. If an unusual load does not exist and a power failure still occurs, contact a qualified electrician or our service department.

Fusing

A 15-amp fuse or circuit breaker should be used when fusing the universal knife grinder. Circuits rated any higher are not adequate to protect the motor from power surges.

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.

Extension Cords

If you find it necessary to use an extension cord with the Model G2790, 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 or damaged.

In the event of an electrical short, grounding reduces the risk of electric shock by providing a path of least resistance to disperse electric cur- rent. This tool is equipped with a power cord hav- ing an equipment-grounding conductor. The out- let must be properly installed and grounded in accordance with all local codes and ordinances.

This equipment must be grounded. Verify that any existing electrical outlet and circuit you intend to plug into is actually ground- ed. 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.
