Extension Cords - Milwaukee 0233-20 Manual Del Operador

Grounded tools require a three wire ex-
tension cord. Double insulated tools can
use either a two or three wire extension
cord. As the distance from the supply out-
let 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 re-
quired 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 con-
tains at least the minimum wire size re-
quired. 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

* Based on limiting the line voltage drop to
five volts at 150% of the rated amperes.

If you are using an extension cord out-
doors, be sure it is marked with the
suffix "W-A" ("W" in Canada) to indi-
cate that it is acceptable for outdoor
use.
Be sure your extension cord is prop-
erly 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.
