Utility Power Connection Notes
Connecting to the utility should be performed only by qualified service personnel and in compliance with local
electrical codes. Connection to utility power must be approved by the local utility before installing the power
supply.
ATTENTION:
UL and NEC require that a service disconnect switch (UL listed) be provided by the installer and be connected
between the power source and the GMX Power Supply. Connection to the power supply must include an
appropriate service entrance weather head.
ATTENTION:
In order to accommodate the high-inrush currents normally associated with the start-up of ferroresonant
transformers (400A, no-trip, first-half cycle), either a “high-magnetic” or HACR (Heating, Air Conditioning,
Refrigeration) trip breaker must be used. Do not replace these breakers with a conventional service entrance
breaker. Alpha recommends ONLY Square D breakers because of increased reliability in this powering
application. High-magnetic Square D circuit breakers and BBX option (UL Listed service entrance) are
available from Alpha Technologies.
