20.3.2
Communications/Electronic Facilities
The A/E shall coordinate the design of all communications/electronics (C/E)
facilities with Chesapeake Division, Naval Facilities Engineering Command
(CHESNAVFACENGCOM FPO-2).
CHESNAVFACENGCOM FPO-2 is the center of expertise for consultation and design
review of C/E facilities.  They provide mission essential technical
consultation and engineering support for the planning, design, construction
and maintenance of Navy executed projects related to C/E facilities.  These
facilities include, but are not limited to, shore based permanent and
relocatable components such as communication centers, transmitters, receivers,
antennas, data processing centers, training facilities, laboratories,
command/control and intelligence centers and cryptographic centers.  Technical
engineering support provided by CHESNAVFACENGCOM FPO-2 includes the
preparation and development of facilities construction criteria for C/E
facilities, including power distribution, power conditioning, HVAC, structural
inspection of antennas, and shielding for RFI, High Altitude Electromagnetic
Pulse (HEMP) and TEMPEST requirements.
The point of contact for C/E facilities is:

20.3.3
Transformers/Unit Substations
a)  Transformer types and ratings shall be indicated on the drawings and
in the specifications.  Size transformers on demand load with 15-20% spare
capacity added for future load growth.
b)  For fire protection reasons, mineral oil transformers are not
permitted on piers or within 25 feet of a building unless special precautions
are taken.  In addition, MIL-HDBK-1008A, "Fire Protection for Facilities
Engineering, Design and Construction", requires that high fire point (less
flammable) liquid transformers which are installed outside buildings adhere to
the same requirements as ordinary mineral oil transformers.  Since there is no
economic justification, high fire point (less flammable) liquid transformers
should not generally be utilized for exterior applications.
c)  Low voltage switchgear should have circuit breakers in lieu of fused
switches as per MIL-HDBK-1004/3, "Switchgear and Relaying", page 11.
d)  Ensure proper clearances around equipment (see MIL-HDBK-1004/2,
"Power Distribution Systems", and the National Electric Code (NEC).
e)  Provide a separate electrical room without mechanical piping (see
MIL-HDBK-1004/2, Section 5 and the NEC).
f)  Provide dual windings on the primary side of all new transformers at
the following ACTIVITIES:
