Double Insulated Tools:
Tools with Two Prong Plugs
Outlets for 2-Prong Plug
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.
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
tools 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 tool damage.
(See Table A on page 6.)
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 tool, 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
suffix “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
qualified electrician before using it.
8. Protect the extension cords from
sharp objects, excessive heat,
and damp or wet areas.
