MIL-HDBK-1012/1
5.2.8.5
Receptacles. All receptacles other than 120-volt, general-purpose
convenience outlets shall be marked with voltage, amperage, phase, and
5.2.8.6
Neutral Conductors. Full-size neutral conductors shall be used
throughout the distribution system.  Requirements for oversized neutral
conductors shall be provided in the BESEP.
5.2.8.7
Grounding Conductors. Greenwire equipment grounding conductors
shall be sized in accordance with NFPA 70.  Requirements for oversized
grounding conductors shall be provided in the BESEP.
5.2.8.8
Cableways.  Cable shall be routed through trays or ducts suspended
overhead.  When raised flooring is used, cable shall be run in conduit within
the space under the floor in accordance with the requirements of NFPA 70.
5.2.8.9
Bus Ducts.
Bus ducts may be used as required.
5.2.8.10
Power Line Transient Protection.  Transient overvoltage
disturbances varying in severity and rate of occurrence are found in all power
distribution systems. Sensitive electronic equipment exposed to these
transients may be disrupted or, in some cases, damaged.  Therefore, surge
protection using Metal Oxide Varistors (MOV's), or similar devices, shall be
installed at the load side of the main distribution switchgear.  Select an MOV
with a rating of less than 125 percent of the root-mean-square (rms) line-to-
ground voltage.  It is recommended that the largest joule rating and the
lowest clamping level for the specific rms voltage rating be selected.
Lighting Systems. Interior lighting, roadway lighting, protective
5.3
lighting, and area lighting systems shall be designed in accordance with MIL-
HDBK-1004/1. Lighting levels shall be in accordance with the latest revision
of the Illuminating Engineers Society (IES) Lighting Handbook, and MIL-HDBK-
1190. In case of conflict, MIL-HDBK-1190 takes precedence over IES criteria.
5.3.1
Emergency Lighting. Battery-powered emergency lighting units shall
be provided in all operational spaces, including the emergency generator rooms
and UPS rooms.  All battery-powered emergency lighting units shall conform to
the requirements of Federal Specification W-L-305, Light Set, General
Illumination (Emergency or Auxiliary).  Special requirements shall be provided
in the BESEP.
5.3.2
Fluorescent Fixtures. Unless otherwise specified in the BESEP,
fluorescent fixtures may be used.  Power line filters shall be installed as
set forth in the BESEP.
5.3.3
Consoles. Consideration should be given to the use of indirect
and/or dimmable lighting in equipment console operating spaces to reduce glare
on equipment display panels.
5.3.4
Antenna Areas. Electric vapor lamps shall not be used within 1/2
mile (805 m) of receiving antennas.
