Grizzly G7211, G7212 Circuit Requirements, 220V Operation Extension Cords, Wiring Diagram

SECTION 2: CIRCUIT REQUIREMENTS

220V Operation Extension Cords

The motor supplied with the G7211 comes prewired for 220V. Refer to the wiring diagram supplied at the back of this manual for more spe- cific information about wiring connections. The G7212 is a 220V, three-phase motor and requires special electrical service. See section on three- phase operation on the next page.

This machine does not come supplied with a plug, therefore a suitable 220V plug must be wired in. When operating at 220V, we recommend using a NEMA-style 6L-15 plug and outlet. See Figure 1. You may also Òhard-wireÓ the machine directly to your panel, provided you place a disconnect switch near the machine. Check the electrical codes in your area for specifics on wiring require- ments.

Under normal use, the motor draws approximate- ly 20 amps @ 220V. We recommend a 25 amp circuit breaker for 220V operation. This should be satisfactory for normal use while providing enough protection against motor damage caused by power surges.

We do not recommend the use of extension cords on 220V equipment. It is much better to arrange the placement of your equipment and the installed wiring to eliminate the need for extension cords. Should it be necessary to use an extension, make sure the cord is rated Hard Service (Grade S) or better. Refer to the chart in Section 1: 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.
