Grounded Tools:

Tools with Three Prong Plugs

3-Prong Plug and Outlet

1. Tools 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 tool 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 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.)

3. The tool 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 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.
