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,
