(c) The 120 V, single-phase, 60 Hz system, derived from the 208 V,
3-phase, 60 Hz system. The 208 V, 3-phase power circuit is separated into
three groups of circuits in the 120 V circuit breaker box. Each group of
circuit breakers is used to supply power to various items of auxiliary
equipment mounted permanently in the van body, as well as additional
equipment installed for tactical purposes.
(2) Power entrance receptacle. The power entrance receptacle (Figure
1) is located on the lower right corner of the van rear panel. A spring-
loaded, hinged cap locks the cable in the receptacle and prevents the
entrance of foreign matter when the cable is removed.
(3) 100 foot power cable and reel. The 100 foot power cable consists
of a four-wire, rubber-insulated cable equipped at one end with a female
receptacle to accommodate the four-prong entrance receptacle and at the
opposite end with a male receptacle designed to fit the female receptacle of
the outside power source. The cable is stowed on the power cable reel. A
canvas boot is provided to protect the cable while in the stowed position.
(4) 36 inch auxiliary power cable. The 36-inch auxiliary power cable
is similar in construction to that of the 100 foot (100') power cable. When
in use, the auxiliary power cable is plugged into the 100' power cable and
the four wires on the auxiliary cable are used to make appropriate
connections to the power source.
