3.4.1.5 Electric plant control panels.
3.4.1.5.1 Desk type EPCP (see 6.3.3). Desk type EPCP (see figure 4) shall be one of the following bench
types:
a.
A horizontal or inclined desk top for plant operation controls.
b.
Inclined desk top for plant operation controls with apron section below.
Desk type EPCP shall have vertical panels for the mounting of instruments, displays, and associated controls. When
specified (see 6.2), desk type EPCP for surface ships shall be provided with a chair that can be mounted so that it
can be swung out of the way when not in use. Requirements for desk type EPCP shall be as specified (see 6.2).
3.4.1.5.1.1 Control switches. Control switches for the electrically-operated circuit breakers controlled from the
EPCP shall be mounted on the desk top and arranged within convenient reach of the operator. Circuit breaker
control switches and their corresponding switches in the mimic bus system shall be located so that their relative
positions as to their locations on the EPCP are similar. Automatic voltage adjusting rheostats shall be mounted close
to the meters being affected by their adjustment. Large equipment which requires infrequent personnel attention
shall be located in the apron portion to conserve panel and desk space. The portion of the apron panel used for
mounting the equipment shall not project beyond the front edge of the desktop. Space shall be provided for filing
the reduced size drawing. Space shall be provided for the mounting of the interior communication (IC) equipment
as specified (see 6.2).
3.4.1.5.2 Vertical EPCP. (see 6.3.13) Vertical EPCP shall be arranged to orient instruments, displays, and
their associated controls near the top, other plant operation controls toward the middle, and larger, infrequently used
equipment at the bottom. Requirements for vertical type EPCP shall be as specified (see 6.2).
3.4.1.5.3 Surface ship EPCP. The following shall be mounted on the EPCP for surface ships:
a. 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 on and operated from the
EPCP (see 6.2).
b.
One AC ammeter for each local generator for reading one phase of generator current.
c.
One AC voltmeter for each local generator for reading one phase of generator potential.
d. One AC voltmeter with transfer switch for reading single-phase voltage of the switchboard bus and of the
bus tie feeders and shore power for switchgear groups containing shore power connection.
e.
One polyphase wattmeter for reading generator output for each local generator.
f. One polyphase wattmeter with transfer switch to indicate the three-phase power output of the remote ship s
service generator (shall be provided where a switchgear group is to have control of a remote generator or
generators).
g. One temperature indicator with selector switch and accessories when temperature detectors are provided
with the generator as specified (see 6.2).
h. One frequency meter for reading the frequency of the generator for each local generator. For units
controlling two local generators, each frequency meter shall be provided with a transfer switch for reading the
frequency of one generator and one bus tie circuit and shore power, in which case 3.4.1.5.3(i) shall be omitted.
i. One frequency meter with transfer switch for reading the frequency of the bus and of each bus tie circuit
and shore power for switchgear group containing shore power connection. For units controlling two local
generators, each frequency meter [see 3.4.1.5.3(h)] shall be provided with a transfer switch for reading the frequency
of one generator and one bus tie circuit and shore power, in which case 3.4.1.5.3(i) shall be omitted.
j. One local control switch, or other control device as required, for control of the speed governor of the
generator prime mover for each local generator.
k. One transfer switch to transfer the governor control of the generator prime mover from local control to the
remote control on the master EPCP. It shall also control the indicator light on the master EPCP to indicate when the
remote station is in control. This transfer switch shall be provided only on EPCPs for which remote control, item (l),
is to be provided on the master EPCP.
