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.)
If you are using one extension cord for more than one tool, add the nameplate am-
peres and use the sum to determine the required minimum cord size.
(See Figure C.)
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.

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