Utility Power Connection Notes
In most cases, the following configurations qualify for service entrance use when wiring a duplex receptacle
to a service disconnect. Other codes may also apply. Always contact your local utility to verify that the wiring
conforms to applicable codes.
120Vac 20A Service, GMX 115V, U.S. Domestic Models
These configurations are equipped with a 120Vac duplex receptacle which provides power to the power
supply and peripheral equipment. The receptacle, NEMA 5-20R, is protected by a single-pole, 20A High
Magnetic (HM) circuit breaker located inside the service entrance. Wiring is typical 12AWG per NEC code,
and a grounding clamp, located on the enclosure, facilitates dedicated grounding.
To bond the box to a neutral plate, use the long green bonding screw provided (Alpha P/N 523-011-10).
