grounded tools:
tools with three prong plugs
1. Tools marked with “Grounding Re-
quired” have a three wire cord and
three prong grounding plug. The
plug must be connected to a properly
grounded outlet. If the tool should
electrically malfunction or break down,
grounding provides a low resistance
path to carry electricity away from
the user, reducing the risk of elec-
tric shock. (See 3-prong plug and
outlet.)
The grounding prong in the plug is
2.
connected through the green wire in-
side 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 3-prong plug
and outlet.)
The tool must be plugged into an
3.
appropriate outlet, properly installed
and grounded in accordance 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
1. Tools marked “Double Insulated” do
not require grounding. They have
a special double insulation system
which satisfies OSHA requirements
and complies with the applicable stan-
dards of Underwriters Laboratories,
Inc., the Canadian Standard Associa-
tion, and the National Electrical Code.
(See outlets for 2-prong plug.)
Double insulated tools may be used
2.
in either of the 120 volt outlets shown
in the preceding illustration. (See
outlets for 2-prong plug.)
extension cords
Grounded 1. 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
2.
increases, you must use a heavier
gauge extension cord. Using exten-
sion 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 number of the 3.
wire, the greater the capacity of the
cord. For example, a 14 gauge cord
