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.)
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.)
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 following illustration.
(See 3-prong plug and Outlet.)

Double Insulated tools: tools with two prong plugs
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 Outlets for 2-prong plug.)
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
Grounded tools require a three wire extension cord. Double Insulated tools can
use either a two or three wire extension cord.
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.)
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.
