Standard Association, and the National Electrical Code.  (See Figure A.)

2.

Double insulated tools may be used in either of the 120 volt outlets shown in the
following illustration.  (See Figure A.)

EXTENSION CORDS

1.

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 Figure B, next page.)

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 Figure B.)

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 Figure B.)

FIGURE 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 Figure B.)

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.
