of electric shock.
(See 3-Prong Plug and Outlet.)
The grounding prong in the Plug is
2.
connected through the green wire
inside the Cord to the grounding
system in the equipment. The green
wire in the Cord must be the only
wire connected to the equipment’s
grounding system and must never be
attached to an electrically “live” termi-
nal.
(See 3-Prong Plug and Outlet.)
The equipment must be plugged into
3.
an appropriate outlet, properly in-
stalled 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.)
Extension Cords
Grounded 1. equipment require a three
wire extension cord. Double Insu-
lated equipment 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 pos-
sible tool damage.
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 Table A.)
When using more than one exten- 3.
sion 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 4.
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 5.
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 prop-
6.
erly wired and in good electrical con-
dition. Always replace a damaged
extension cord or have it repaired by
a qualified electrician before using it.
Protect the extension cords from
7.
sharp objects, excessive heat, and
damp or wet areas.
