The use of larger gauge stranded aluminum wire (larger than #8 AWG) is fairly common in much of North America for modern residential construction. Aluminum wire is used in residential applications for lower voltage service feeders from the utility to the building. This is installed with materials and methods as specified by the local electrical ...
The data link connector (DLC) is the multi-pin diagnostic connection port for automobiles, trucks, and motorcycles used to interface a scan tool with the control modules of a given vehicle and access on-board diagnostics and live data streams. [1] Prior to 1996, many OBD-I data link connector's were in the engine compartment, usually near the ...
A separate pilot wire is run from distribution/ equipment supply system in addition to earth wire, to supervise the continuity of the wire. This is used in the trailing cables of mining machinery. [19] If the earth wire is broken, the pilot wire allows a sensing device at the source end to interrupt power to the machine.
The characteristic impedance of twin lead is a function of the insulating material and its thickness, and the wire diameter and its spacing; in the most common type, 300 Ω twin-lead ribbon cable, the wire is usually AWG 20 or 22 (0.52 or 0.33 mm²), about 7.5 millimetres (0.30 in) apart.
Serial cables are typically used for RS-232 communication.. A serial cable or RS-232 cable is a cable used to transfer information between two devices using a serial communication protocol.
The ALDL communications link was originally developed at the General Motors Emissions Control Systems Project Center located at GM's Milford, Michigan Proving ground. The center was responsible for coordinating all divisional and staff design, testing and development activities of the emission control system for GM USA passenger vehicles ...
The standard defines a 2-wire 18 gauge wire cable that can run up to 130 feet (40 m) and operates at 9600 bit/s. A message is composed of up to 21 characters, unless the engine is stopped and the vehicle is not moving in which case transmitters are allowed to exceed the 21 byte max message length.
The first rubber-insulated cables for US building wiring were introduced in 1922 with US patent 1458803, Burley, Harry & Rooney, Henry, "Insulated electric wire", issued 1923-06-12, assigned to Boston Insulated Wire and Cable . These were two or more solid copper electrical wires with rubber insulation, plus woven cotton cloth over each ...
