resistance path to carry electricity away from the user, reducing the risk of electric
shock.

(See figure A.)

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 figure A.)

Your 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.

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 figure B.)

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

(See figure B.)

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 seri-
ous drop in voltage, resulting in loss of power and possible tool damage.
(See figure c, next page.)

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.)

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.)
