electric 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.)
EXTENSION CORDS
Grounded tools require a three wire 1.
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.
(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
can carry a higher current than a 16
gauge Cord. (See Table A.)
When using more than one Exten-4.
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 5.
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 6.
outdoors, make sure it is marked with
the sufx “W-A” (“W” in Canada) to
indicate it is acceptable for outdoor
use.
Make sure the Extension Cord is 7.
properly wired and in good electrical
condition. Always replace a damaged
Extension Cord or have it repaired by
a qualied electrician before using it.
Protect the Extension Cords from 8.
sharp objects, excessive heat, and
damp or wet areas.
