EXTENSION CORDS
Grounded tools require a three wire extension
cord. Double insulated tools can use either a two
or three wire extension cord. 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. Refer to the table shown to determine the
required minimum wire size.
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.
When using more than one extension cord to make
up the total length, be sure each cord contains at
least the minimum wire size required. 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 wire size.
Guidelines for Using Extension Cords
• If you are using an extension cord outdoors, be sure
it is marked with the suffix "W-A" ("W" in Canada) to
indicate that it is acceptable for outdoor use.
• Be 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
person before using it.
• Protect your extension cords from sharp objects,
excessive heat and damp or wet areas.
