Ewis Is
An electrical wiring interconnect system (EWIS) is the wiring system and components (such as bundle clamps, wire splices, etc.) for a complex system. The term originated in the aviation Industry (economics), 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. Background Prior to the aviation accidents of TWA Flight 800 and SwissAir 111, the wiring on aircraft was a minor concern. In response to these accidents, the Aging Transport Systems Rulemaking Advisory Committee (ATSRAC) was chartered to gather industry leaders examine the current state of aging aircraft systems; one of the main areas examined included EWIS. The committee included a number of key organizations and businesses including Airlines for America, ATA, NASA, Northwest Airlines, Boeing, Airbus, FAA, and Electromechanical Design Company. Many of the results from ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wiring
Electrical wiring is an electrical installation of cabling and associated devices such as switches, distribution boards, sockets, and light fittings in a structure. Wiring is subject to safety standards for design and installation. Allowable wire and electrical cable, cable types and sizes are specified according to the circuit operating voltage and electric current capability, with further restrictions on the environmental conditions, such as ambient temperature range, moisture levels, and exposure to sunlight and chemicals. Associated circuit protection, control, and distribution devices within a building's wiring system are subject to voltage, current, and functional specifications. Wiring safety codes vary by locality, country, or region. The International Electrotechnical Commission (IEC) is attempting to harmonise wiring standards among member countries, but significant variations in design and installation requirements still exist. Wiring codes of practice and regulat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
