Extension Cords

Using extension cords is not 

recommended. The use of extension 

cords will cause voltage to drop  

resulting in power loss to the motor 

and overheating.
Instead of using an extension cord, 

increase the working reach of the 

air hose by attaching another length 

of hose to its end. Attach additional 

lengths of hose as needed.
If an extension cord must be used, be 
sure it is:
• 

a 3-wire extension cord that has 
a 3-blade grounding plug, and a 
3-slot receptacle that will accept 
the plug on the product

• 

in good condition

• 

no longer than 50 feet

• 

12 gauge (AWG) or larger.  (Wire 

size increases as gauge number 

decreases.  10 AWG and 8 AWG 

may also be used.  DO NOT USE 

14 OR 16 AWG.)

Voltage and Circuit Protection

Refer to the specification chart for the 
voltage and minimum branch circuit 
requirements.

Certain air 

compressors can 

be operated on a 15 amp circuit if 

the following conditions are met. 

1.  Voltage supply to circuit must 

comply with the National 
Electrical Code.

2.  Circuit is not used to supply any 

other electrical needs.

3.  Extension cords comply with 

specifications.

4.  Circuit is equipped with a 15 amp 

circuit breaker or 15 amp time 
delay fuse. 

NOTE:

 If compressor 

is connected to a circuit 
protected by fuses, use only time 
delay fuses. Time delay fuses 
should be marked "D" in Canada 
and "T" in the US. 

If any of the above conditions 
cannot be met, or if operation of 
the compressor repeatedly causes 
interruption of the power, it may be 
necessary to operate it from a 20 amp 
circuit. It is not necessary to change 
the cord set.
