5 AC Input Panels
Overview
AC Service
The ac input panel provides the facility to terminate 3-phase ac service to the GPS2436 system
or to distribute individual 1-phase ac supplies to each of the system rectifier positions.
Depending upon the option ordered, the panel will connect 3-wire (three phases), 4-wire (three
phases + neutral), or individual 2-wire (single phase, either 2 hot leads or 1 hot lead and neutral)
input ac service.
Some options provide circuit breakers to protect the conductors providing ac service to the
individual rectifiers. Other systems contain a terminal strip and the conductors are protected by
circuit breakers located in the building’s ac service panel.
Note: All wire sizes based on the US National Electric Code.
