EWIS ELECTRICAL WIRING INTERCONNECTION SYST

An electrical wiring interconnect system (EWIS) is the wiring system and components (such and bundle clamps, wire splices, etc.) for a complex system. The term originated in the aviation industry but was originally designated as Electrical Interconnection Systems (EIS).The change from EIS to EWIS was done to emphasize the focus on the actual wires and wiring of the systems throughout aircraft.

EWIS BACKGROUND

Safety concerns about wiring systems in airplanes were brought to the forefront of public attention by a midair explosion in 1996 involving a B747 airplane.

Ignition of flammable vapors in the fuel tank was the probable cause of that fatal accident, and the most likely source was a wiring failure that allowed a spark to enter the fuel tank. All 230 people aboard the airplane were killed.
