Double Insulated Tools: Tools 

with Two Prong Plugs

Outlets for 2-Prong Plug

1.  Tools marked “Double Insulated” do not 

require grounding.  They have a special 
double insulation system which satisfies OSHA 
requirements and complies with the applicable 
standards of Underwriters Laboratories, Inc., 
the Canadian Standard Association, 
and the National Electrical Code.

2.  Double insulated tools may be used in either of the 

120 volt outlets shown in the preceding illustration.   

(See Outlets for 2-Prong Plug.)

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.
