Wiring (Continued)
Make sure voltage is correct with the motor wiring.
NOTE: If using 208 volts single phase, make sure the motor name plate states it is rated
for 208 volts single phase. 230 volt single phase motors do not work on 208 volts unless
they have the 208 volt rating.

Recommended wire sizes may be larger than the minimum set up by local ordinances.
If so, the larger size wire should be used to prevent excessive line voltage drop. The
additional wire cost is very small compared with the cost of repairing or replacing a
motor electrically "starved" by the use of supply wires which are too small.
Grounding
This product must be grounded. Grounding reduces the risk of electrical shock by providing an escape wire
for the electric current if short circuit occurs. This product must be installed and hard wired into an electrical
disconnect box or breaker that is dedicated to this piece of equipment and meets all local electrical codes.
Breakers and Fuses
The entire electrical system should be checked by a certified electrician. Time delay breakers and fuses are
required for this compressor. A tripped breaker or blown fuses may indicate a direct short to ground, high current
draw, improper wiring, incorrect fuse or breaker size and/or type. This needs to be evaluated by a certified
electrician.
Motor Hookup and Starter Installation
Branch circuit protection must be provided as specified in the United States National Electrical Code, Chapter
2, "Wiring Design and Protection." Article 210, using the applicable article "For Motors and Motor Controllers,"
(Article 430, Table 430-1 52). Unit comes with motor starter and overload installed. The overloads should be set
to 125% of the full load amp rating of the motor name plate.
