EXTENSION CORDS
DOUBLE INSULATED TOOLS: TOOLS WITH TWO PRONG PLUGS
Tools marked “Double Insulated” do not require grounding. They have a special
1.
double insulation system which satisfies OSHA requirements and complies with
the applicable standards of Underwriters Laboratories, Inc., the CanadianStan-
dard 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
2.
following illustration.
(See Figure B.)

2-PRONG PLUG
Grounded tools require a three wire extension cord. Double Insulated tools can use
1.
either a two or three wire extension cord.
As the distance from the supply outlet increases, you must use a heavier gauge
2.
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 Table A.)
The smaller the gauge number of the wire, the greater the capacity of the cord. For
3.
example, a 14 gauge cord can carry a higher current than a 16 gauge cord.
(See Table A.)
When using more than one extension cord to make up the total length, make sure
4.
each cord contains at least the minimum wire size required. (See Table A.)
If you are using one extension cord for more than one tool, add the nameplate am-
5.
peres and use the sum to determine the required minimum cord size.
(See Table A.)
If you are using an extension cord outdoors, make sure it is marked with the suffix
6.
“W-A” (“W” in Canada) to indicate it is acceptable for outdoor use.
