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.  [H$$&J)4($&I/\
3.  The smaller the gauge number of the wire, the 
greater the capacity of the cord.  For example, 
a 14 gauge cord can carry a higher current 
than a 16 gauge cord.  [H$$&J)4($&I/\
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.  [H$$&J)4($&I/\
5.  If you are using one extension cord for more 
than one tool, add the nameplate&eres 
and use the sum to determine the required 
minimum cord size.  [H$$&J)4($&I/\
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.
