10.1.2.2
All other patient care areas will be treated as "General Care."
WET LOCATIONS. Those patient care areas that are normally subject
10.1.2.3
to wet conditions [see paragraph 10.3.13, " GROUND-FAULT CIRCUIT-INTERRUPTERS
(GFCI)"] including standing water on the floor, or routine dousing or
drenching of work areas and those areas defined in NFPA-99 and 70. Routine
housekeeping procedures and incidental spillage of liquids are not defined as
wet locations. Operating rooms, delivery rooms, cystoscope rooms, oral
surgery, cardiac catherization rooms and other such rooms are not wet areas.
10.2
EXTERIOR ELECTRICAL.
10.2.1
Exterior electrical systems shall conform to ANSI-C2, "National
Electrical Safety Code," except where Service technical criteria have more
stringent requirements.
COMMON VOLTAGES. 4.16kv, 12.47kv, 13.2kv, 13.8kv and 34.5kv are
10.2.1.1
common distribution voltages for military installations. However, 12.47kv,
13.2kv, and 13.8kv are the normal distribution voltages serving medical
facilities.
NORMAL SOURCE SITE INVESTIGATION. Site electrical evaluation
10.2.2
shall meet the requirements of Section 2, "DESIGN PROCEDURES, SUBMITTALS, AND
DOCUMENTATION."Coordinate electrical utility siting with other utilities.
Provide underground distribution on site, and visual screening by location or
landscaping elements, where appropriate for the project, to improve overall
site aesthetics.
NORMAL HOSPITAL SOURCE. For electrical design criteria
10.2.3
related to power supply, see documents listed in "TABLE 10-1 APPLICABLE
REFERENCES." Hospitals will be served by two primary service feeders each
serving one end of a double-ended substation or to a selector switch serving a
multi-ended network substation (See ANNEX B for additional criteria
requirements related to the multi-ended network substation). Each feeder
shall be able to carry the full hospital demand plus 20 percent spare load
growth, and shall be installed underground within the hospital site. Dual
primary feeders serving both ends of a double-ended substation, through a
primary selector switch, as illustrated in Figure 10-1 of MIL-HDBK-1191 must
have prior approval of the design agency before incorporation into a design.
Service feeders will be connected to different power sources, if available,
and to two differently routed distribution system feeders. Where two power
sources are not available, the service feeders may be connected to two
different sections of a loop system. Manually operated primary selector
switch and fused load break disconnect switch will be provided for each
transformer as indicated in Figure 10-1. Transformers will normally be
located outside the hospital, but may be located within the building where
