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.
