Wiring
Requirements
3.4.1 Introduction
The installing agency shall supply and fabricate all external cables
and mating connectors. The length and routing of external cables
should be carefully studied and planned before attempting
installation of the equipment. Allow adequate space for installation
of cable and connectors. Avoid sharp bends and placing cables
near aircraft control cables. Maintain a minimum clearance of three
(3) inches from any control cable. If wiring is run parallel to
combustible fluid or oxygen lines, maintain a separation of six (6)
inches between the lines.
3.4.2 Power
Wires
The amplifier power and ground wires (P2-A, B) shall be 16 AWG,
MINIMUM shielded twisted pair with the shield properly bonded at
one end only. Power ground wires shall be bonded to electrically

impedance. Additionally, ensure that the chassis grounding post is
bonded to aircraft frame
ZLWK UHVLVWDQFHRU LPSHGDQFH
All wires shall be in accordance with the standard military
specification of MIL-W-22759 or equivalent. Protect power wires
with circuit breakers or fuses located close to the electrical power
source bus.
3.4.3 Audio
Lines
All audio lines require 22 AWG, MINIMUM
,
twisted shielded cable
with the cable shields grounded at the source. Twisted, shielded
cable shall be in accordance with the standard military specification
of MIL-DTL-27500 or equivalent.
