MIL-DTL-16036M(SH)
b. One indicator light (white) per shore power receptacle to indicate the shore power feeder is energized. One
indicator light (white) to indicate the bus feeder is energized. These indicator lights shall be mounted near the shore
power circuit breakers.
c.
Indicator lights (blue) to indicate that each shore power circuit breaker is closed.
d. One switchboard type phase sequence indicator with a multiposition selector switch for use in checking
phase rotation and orientation of shore power connections (see figure 2). Two indicator lights (green) to indicate
phase orientation.
e. One transfer switch for use with the generator unit frequency meter for reading the frequency of the bus tie
circuit and shore power.
f.
One reference selector switch for use in checking phase orientation of shore power connections.
g.
One AC ammeter for reading shore power current.
h. For shore power switchboard units with more than four shore power breakers installed, one multiposition
selector switch to allow one of a selected number of different shore power receptacles to act as the master circuit.
Necessary devices, including potential transformers, shall be provided on this receptacle circuit for metering and
synchronizing of shore power and the switchboard bus across the shore power breakers.
3.4.1.2 AC generator control unit for switchgear groups not having an EPCP or an EPCC. (see figure 3 for a
typical one-line diagram) Devices listed in 3.4.1.1, except item (l), shall be mounted on or within the unit.
3.4.1.2.1 Front panel. The following devices shall be mounted on the front panel of the generator unit:
a.
One AC ammeter for reading one phase of generator current.
b. One AC voltmeter with transfer switch for reading one phase of generator potential, one phase of each bus
tie voltage, and one phase of shore power voltage for switchgear group containing shore power connection.
c.
One polyphase wattmeter for reading generator output.
d.
One frequency meter for reading the frequency of the generator.
e.
One control switch for control of the generator circuit breaker where an electrically-operated breaker is
used.
f. Control switches, rheostats, and similar devices, as required (see 6.2) in conjunction with the governor
speed regulation of the generator prime mover.
g. One transfer switch to transfer the governor control from the local control switch to the remote control
switch on the AC bus tie unit (or control unit) of the control switchgear group. It shall also control the lamp [see
3.4.1.4.1(c)] on the bus tie unit or control unit to indicate when the remote switch is in control. This shall be
provided only when the unit has control of a remote generator.
h. One control switch with indicator light (white) for control of the generator space heaters when provided
with the generator as specified (see 6.2).
i. Control switches, rheostats, and similar equipment that is for panel mounting and is required in conjunction
with the voltage regulator equipment mounted in the generator unit shall be mounted and operated from the front
panel (see 6.2).
j. For installations in which a bus tie unit is not provided, one set of three indicator lights (clear) with a
control switch, to indicate ground conditions on the main bus or any of its feeders, shall be mounted on the front
panel of the generator unit.
k. One synchroscope and one set of synchronizing lights (clear) with transfer switch for synchronizing the
generator with the main bus, and the main bus with the bus tie circuit, and the bus tie with shore power for
switchgear group containing shore power connection mounted and operated from the front panel.
l. One Type I synchronizing control equipment shall be provided for each single or two generator
switchgroup. The synchronizing control monitor may be mounted in the bus tie unit instead of the generator control
unit.
m. One Type II automatic paralleling device, if required (see 6.2). The automatic paralleling device may be
mounted in the bus tie unit instead of the generator control unit.
