What is Wire Gauge?
Posted by Mark Strittmatter on July 18, 2016
Wire gauge is extremely important to the aircraft that InterConnect Wiring supports. Wire gauge is the measurement of the diameter of a wire, or the thickness of the wire. There are various wire gauges used within UH-60 wiring harnesses, F-15 wiring harnesses, C-130 electrical wiring harnesses, etc. The thickness determines the amount of electrical current • Read More >>

What is Megohm or Megger Testing?
Posted by Mike Winters on July 11, 2016
What comes to mind when contemplating the strength of a wire? A lot of people only consider what can be seen on the outside. For example, how far the wire can be pulled before it breaks or how high of a temperature it can withstand before it melts. But what about breakdowns in the integrity • Read More >>

What is an Insert Arrangement?
Posted by Eric Evans on July 4, 2016
The highly advanced military aircraft of today, such as the Lockheed Martin F-35 fighter or Boeing B-1 bomber, contain a large amount of specialized electrical equipment. Some examples include relay panels, circuit breaker panels, mux transformer panels, audio panels, navigation computers, weapons computers, and many more. This equipment is essential in enabling the aircraft to complete its designed mission, • Read More >>

What is a Cable Shield Termination?
Posted by Michael Janney on June 27, 2016
In the commercial aerospace and defense industry we find a high concentration of electrical wiring in a relatively small area. The overall goal is to design the equipment and components as small as practical and locate the equipment in a compact, easily accessible area. This includes all wiring harnesses, cable assemblies, and aircraft relay panels. A small space • Read More >>
What is Crosstalk in a Wiring Harness?
Posted by Nam Tran on June 20, 2016
Did you ever wonder why some wires are bundled together in one aircraft wiring harness and others are not? Why does this wiring harness have 6 breakouts while this other harness has only two? Why didn’t the Lockheed Martin, Boeing, or InterConnect engineer just add those two wires to the larger harness? There are several reasons, but one • Read More >>

What is a HAD?
Posted by Chris Bettinger on June 13, 2016
A HAD is a Harness Assembly Drawing used to aid in the manufacturing of electrical wiring harnesses. HADs are used in the aerospace industry for all aircraft platforms including the AH-1F, AH-1Z, B-1B, B-52, C-130, EC-130, F-15, F-16, F-22, etc. Before production of a harness, a HAD is printed in full scale (1:1) to ensure the • Read More >>

What does it Mean to “Beep Out” a Wiring Harness?
Posted by Clare McGarrey on June 6, 2016
Wiring harnesses are crucial to aircraft as well as anything that requires electrical power. Often InterConnect has customers approach us because they have a project that is behind schedule, there’s an inoperable aircraft on ground, or a crucial modification needing to take place in the field before the aircraft can be mission ready. Our customers • Read More >>
What is a routing list?
Posted by John Ashour on May 30, 2016
A routing list (commonly called an ‘RL’) for an aircraft is a list of each wire in a wiring harness. Routing Lists are used on all aircraft including F-16, F-22, F-35, V-22, UH-60, CH-53K, etc. It is called ‘routing’ because it contains the endpoints of each wire. For example, wire NAV-121-22 may go from reference • Read More >>

Why Does Each Wire on an Airplane Have Its Own Identification Number?
Posted by Marc Piloian on May 24, 2016
In brief – to ensure the airworthiness of the aircraft. Any modern aircraft, especially fighters like the F-15, F-16, F-22 and F-35 have thousands of wires. The integrity of the electrical wiring interconnect system (EWIS) affects the ability to gather data, communicate, fire weapons and even control the aircraft in flight. Now imagine you’re a • Read More >>
