SECTION II. DESCRIPTION AND DATA
1-7. Description. In addition to the description provided here, refer to TM 32-5865-012-10 for a general
description and illustration of the power distribution box. The power distribution box is a metal enclosure
containing 21 circuit breakers, one toggle switch, one lamp mounted on the front panel, and 11 multipin
connectors mounted on the rear panel. Each circuit breaker protects a 115 V ac, 400-Hz, three-phase or a +28
V dc circuit to external line replaceable units (LRUs) in the system. The toggle switch operates relays in the
power distribution box to control the application of power to some circuits and to function as an interlock control
for another circuit. The lamp is illuminated when mission power is applied through the power distribution box to
the LRUs in the system. In addition to the functions performed by the circuit breakers, the power distribution
box contains interlock jumpers as safety features on input and output connectors. Rear panel connectors J9,
J10, and Jl11 are part of an RF interference (RFI) filter assembly in the power distribution box. The RFI filter
assembly filters six of the +28 V dc outputs. Power distribution box power and input/output connections are
made at the rear panel (see table 1-1).
