Electric connections on aircraft

Jerome H. Ehrich (nonmember; lieutenant, Air Technical Service Command, Wright Field, Dayton, Ohio): This paper presents an interesting survey of electric connections in common use in aircraft. In regard to stripping of wire, a table is included, showing allowable broken strands per wire and a maximum allowable percentage of scraped, swaged or nicked strands. The insulation-stripping operation should be accomplished without damaging or breaking any of the wire strands. Setting up of standards for permissible damage to wire will result in careless wire stripping. An employee who knows that a certain number of strands may be severed or damaged in the stripping operation may make no special effort to strip a wire without damage to the wire strands.
