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 Figure C.)
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 C.)
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 C.)
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 C.)
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 acceptab le f or outdoor use .
7 . 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.
8 . Protect your extension cords from sharp objects, excessive heat, and damp or wet
areas.
