Extension cords may be used to power devices that are located at a 
distance from the generator.  However, use only UL-listed, outdoor-rated, 
grounded extension cords of the proper size.  Use Table 2 below to choose 
an adequately sized extension cord according to the amperage of the 
device being used and the length of the cord.

WARNING:   

Use of under sized extension cords can cause electric shock, fire, or 
damage to connected devices. 

 

 

 

All extension and appliance cords must be in good condition and not worn, 
bare, frayed, or otherwise damaged. 

 

     

WARNING: 

Use of damaged electric cords can cause electric shock or fire.

 

 

Note:  If an extension cord becomes hot to the touch, it is overloaded or 
damaged and must be replaced. 

 

Northern Tool is NOT responsible for damage or injury resulting from 
customer use of inadequate extension cords.
