2. 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 Polisher’s grounding system and must never be attached to an electrically
“live” terminal. (See Figure A.)
3. A grounded appliance 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 following illustration. (See Figure A.)

DOUBLE INSULATED APPLIANCES: APPLIANCES WITH TWO PRONG PLUGS
1. Appliances marked “Double Insulated” do not require grounding. They have a special double
insulation system which satisfies OSHA requirements and complies with the applicable
standards of Underwriters Laboratories, Inc., the Canadian Standard Association, and the
National Electrical Code. (See Figure B.)
2. Double insulated tools may be used in either of the 120 volt outlets shown in the following
illustration. (See Figure B.)

EXTENSION CORDS
1.
Grounded appliances require a three wire extension cord.
Double Insulated products 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. (See Figure C, next page.)
3. 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. (See Figure C.)
4. When using more than one extension cord to make up the total length, make sure each cord
contains at least the minimum wire size required. (See Figure C.)
