Extension Cords
Use extra air hose instead of an extension cord to avoid voltage drop and
power loss to the motor, and to prevent overheating.
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 Parts Manual 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 through branch circuit is 15 amps.
2. Circuit is not used to supply any other electrical needs (lights, appliances,
etc.).
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.
