Routing Precautions When wiring must be routed parallel to combustible fluid or oxygen lines for short distances, as much separation as possible should be maintained. The wires should be on a level with, or above, the plumbing lines. Clamps should ... spaced so that if a wire is broken at a clamp, it will not contact the line. Where a 6-inch separation is not possible, both the wire bundle and the plumbing line can be clamped to the same structure…

Electrical Wiring Installation The following recommended procedures for installing aircraft electrical wiring are typical of those used on most types of aircraft. For purposes of this discussion, the following definitions are applicable: 1. Open wiring—any wire, wire group ... wire bundle not enclosed in conduit. 2. Wire group—two or more wires in the same location, tied together to identity the group. 3. Wire bundle—two or more wire groups tied together because they are going in the same…

Wire Installation & Routing Open Wiring Interconnecting wire is used in point-to-point open harnesses, normally in the interior or pressurized fuselage, with each wire providing enough insulation to resist damage from handling and service exposure. Electrical wiring is often ... installed in aircraft without special enclosing means. This practice is known as open wiring and offers the advantages of ease of maintenance and reduced weight.
