The grounding prong in the plug is   connected through the green wire   inside the cord to the grounding   system in the tool. The green wire   in the cord must be the only wire   connected to the tool’s grounding   system and must never be attached   to an electrically “live” terminal. (see   3-prong plug and outlet.)   warninG   electric sHock   and deatH FroM   incorrect GroundinG   wire connection:   Check with a qualified   electrician if you are in doubt   as to whether the outlet is   properly grounded. do not   modify the power cord plug   provided with the tool. never   remove the grounding prong   from the plug. do not use the   tool if the power cord or plug   is damaged. if damaged, have   it repaired by a service facility   before use. if the plug will not   fit the outlet, have a proper   outlet installed by a qualified   electrician.   3. The tool must be plugged into an   appropriate outlet, properly installed   and grounded in accordance with all   codes and ordinances. The plug and   outlet should look like those in the   preceding illustration. (see 3-prong   plug and outlet.)   4. note: tHis belt/disc   sander Has a tHree-pronG   Grounded pluG.   Grounded tools: tools with three   prong plugs   extension cords   1. Grounded tools require a three wire   extension cord. Double insulated   tools can use either a two or three   wire extension cord.   2. As the distance from the supply   outlet increases, you must use a   heavier gauge extension cord. Using   extension cords with inadequately   sized wire causes a serious drop in   voltage, resulting in loss of power and   possible tool damage.   3-prong plug and outlet   1. Tools marked with “Grounding   Required” have a three wire cord   and three prong grounding plug.   The plug must be connected to a   properly grounded outlet. If the tool   should electrically malfunction or   break down, grounding provides a   low resistance path to carry electricity   away from the user, reducing the risk   (see table a.) The smaller the   gauge number of the wire, the   greater the capacity of the cord. For   example, a 14 gauge cord can carry   a higher current than a 16 gauge   cord.
