WET LOCATIONS. Those patient care areas that are normally subject
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.
Exterior electrical systems shall conform to ANSI-C2, "National
Electrical Safety Code," except where Service technical criteria have more

NORMAL HOSPITAL SOURCE. For electrical design criteria
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 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
