serious drop in voltage, resulting in loss of power and possible tool damage.
(See Figure C, 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 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 acceptable for 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.
