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
standards of Underwriters Laboratories, Inc., the Canadian Standard Association, and the
National Electrical Code.
(See Outlets for 2-Prong Plug.)
2.
Double insulated tools 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 products require a three wire extension cord. Double Insulated tools 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 product 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 product, add the nameplate
amperes
and use the sum to determine the required minimum cord size.
(See Table A.)
6.
Make sure your extension cord is properly wired and in good electrical condition. Always
replace a damaged extension cord or have it repaired by a qualified electrician before
using it.
7.
Protect your extension cords from sharp objects, excessive heat, and damp or wet areas.
