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.
