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 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.
