Harbor Freight Tools 95630 Double Insulated Tools Tools with Two Prong Plugs, Extension Cords

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 of electric shock. (See 3-Prong Plug and Outlet.)

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 tool’s grounding system and must never be attached to an electrically “live” terminal.

(See 3-Prong Plug and Outlet.)

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.)

Double Insulated Tools: Tools with Two Prong Plugs

Outlets for 2-Prong Plug

1.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.

2.Double insulated tools may be used in either of the 120 volt outlets shown in the preceding illustration.

(See Outlets for 2-Prong Plug.)

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.

(See Table A on page <?>.)

3.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.

4.Protect the extension cords from sharp objects, excessive heat, and damp or wet areas
