DIAGRAM A

DOUBLE INSULATED TOOLS: TOOLS WITH TWO PRONG PLUGS

4.

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 Diagram B.)

5.

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

DIAGRAM B

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 Diagram C, next page.)

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 Diagram C.)

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 Diagram C.)
