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.)
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.)
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.
