Grounded tools: tools with three prong plugs
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 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
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.
