Grounding
TO PREVENT ELECTRIC
SHOCK AND DEATH FROM
INCORRECT GROUNDING WIRE
CONNECTION:
Check with a qualied electrician if you are
in doubt as to whether the outlet is properly
grounded. Do not modify the power cord
plug provided with the device. Never
remove the grounding prong from the plug.
Do not use the device if the power cord or
plug is damaged. If damaged, have it
repaired by a service facility before use. If
the plug will not t the outlet, have a proper
outlet installed by a qualied electrician.
Grounded Devices: Devices
with Three Prong Plugs
3-Prong Plug and Outlet
1. Devices marked with “Grounding Required” have a
three wire cord and three prong grounding plug. The
plug must be connected to a properly grounded outlet.
If the device should electrically malfunction or break
down, grounding provides a low resistance path to
carry electricity away from the user, reducing the risk
of electric shock. (See 3-Prong Plug and Outlet.)
2. The grounding prong in the plug is connected through
the green wire inside the cord to the grounding system
in the device. The green wire in the cord must be
the only wire connected to the device’s grounding
system and must never be attached to an electrically
“live” terminal. (See 3-Prong Plug and Outlet.)
3. The device must be plugged into an 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 Devices:
Devices with Two Prong Plugs
Outlets for 2-Prong Plug
1. Devices marked “Double Insulated” do not require
grounding. They have a special double insulation
system which satises OSHA requirements
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.)
2. Double insulated devices may be used in either
of the 120 volt outlets shown in the preceding
illustration. (See Outlets for 2-Prong Plug.)
Extension Cords
1. Grounded devices require a three wire extension
cord. Double Insulated devices can use
either a two or three wire extension cord.
2. 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 device damage.
(See Table A.)
3. 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.)
4. 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.)
5. If you are using one extension cord for more
than one device, add the nameplate amperes
and use the sum to determine the required
minimum cord size. (See Table A.)
6. If you are using an extension cord outdoors, make
sure it is marked with the sufx “W-A” (“W” in
Canada) to indicate it is acceptable for outdoor use.
7. Make sure the extension cord is properly wired
and in good electrical condition. Always replace
a damaged extension cord or have it repaired
by a qualied electrician before using it.
8. Protect the extension cords from sharp objects,
