exTeNsION CORDs
Grounded
1.
tools require a three wire extension cord.
As the distance from the supply outlet increases, you must use a heavier gauge
2.
extension cord. Using extension cords with inadequately sized wire causes a seri-
ous drop in voltage, resulting in loss of power and possible tool damage.
(see Table A.)
The smaller the gauge number of the wire, the greater the capacity of the cord. For
3.
example, a 14 gauge cord can carry a higher current than a 16 gauge cord.
(see Table A.)
When using more than one extension cord to make up the total length, make sure
4.
each cord contains at least the minimum wire size required.
(see Table A.)
If you are using one extension cord for more than one tool, add the nameplate
5.
am-
peres and use the sum to determine the required minimum cord size.
(see Table A.)
If you are using an extension cord outdoors, make sure it is marked with the suffix
6.
“W-A” (“W” in Canada) to indicate it is acceptable for outdoor use.
Make sure your extension cord is properly wired and in good electrical condition.
7.
Always replace a damaged extension cord or have it repaired by a qualified electri-
cian before using it.
Protect your extension cords from sharp objects, excessive heat, and damp or wet
