Double Insulated Tools with Two Prong Plugs

4.A polarized plug (one blade is wider than the other) is a feature to reduce the risk of electric shock. This plug will fit in a polarized outlet only one way. If the plug does not fit fully in the outlet, reverse the plug. If it still does not fit, contact a qualified electrician. Never use with an extension cord unless plug can be fully inserted. Do not alter the plug.”

5.Tools 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 above.)

6.Double insulated tools may be used in either of the 120 volt outlets shown in the following illustration. (See Figure B above.)

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. (See Table A.)

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 Table A.)

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 Table A.)

5.If you are using one extension cord for more than one tool, add the nameplate amperes and use the sum to determine the required minimum cord size. (Table A.)

6.If you are using an extension cord outdoors, make sure it is marked with the suffix “W- A” (“W” in Canada) to indicate it is acceptable for outdoor use.

7.Make sure your extension cord is properly wired and in good electrical condition. Always replace a damaged extension cord or have it repaired by a qualified electrician before using it.

8.Protect your extension cords from sharp objects, excessive heat, and damp or wet areas.
