The tool must be plugged into an appropriate
outlet, properly installed and grounded in ac-
cordance with all codes and ordinances. The
plug and outlet should look like those in the
preceding illustration.
(see 3-prong plug
and Outlet.)
double insulated tools: tools
with two prong plugs
Outlets for 2-prong plug
Tools marked “Double Insulated” do not re-
quire grounding. They have a special double
insulation system which satisfies OSHA re
-
quirements 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 exten-
sion 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 num-
ber 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 table a.)
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 table a.)
If you are using one extension cord for more
than one tool, add the nameplate
amperes
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 “W-A”
(“W” in Canada) to indicate it is acceptable
for outdoor use.
Make sure the extension cord is properly
wired and in good electrical condition. Al-
ways replace a damaged extension cord
or have it repaired by a qualified electrician
before using it.
Protect the extension cords from sharp
objects, excessive heat, and damp or wet
areas.
