Unit 5. Components of the electrical system Text a wires
Wires provide a path for electrical current to flow. The metal wire itself is called a conductor because it conducts, or carries, the current. The conductor covered with insulation to keep the current in its correct path, i.e. to prevent short circuits.
Wire comes in many sizes and types. Some wire manufacturers call all their products wire, others prefer the term cable. The main difference between a wire and a cable is size, i.e. the effective diameter of the conductor. Because a cable must carry a great deal of amperage to operate the starter motor, or a great deal of voltage to operate the sparkplugs, it is relatively large in diameter.
Wires, on the other hand, must carry relatively less amperage, so they have noticeably smaller diameters than cables. The term ‘cable’ is used to identify the main conductors used in the starting and secondary-ignition circuits and at the battery. All other conductors in the system are called wires.
The conductor diameter of a wire or cable is carefully matched to the amperage the wire is expected to carry. It is measured in one of two ways.
Gage (Am. for gauge) is the standard SAE designation for wire sizes, usually referred to as AWG (American Wire Gage). Gages are not measurements of actual dimensions, but are arbitrary numbers that indicate relative diameters. And, unlike dimensional measurements, the larger the gage number, the smaller the wire. Gages used in automotive wiring range from 10 (the largest wire diameter) to 20 (the smallest wire diameter). Cables range from 00 (largest) to 6 (smallest). The size distinction between wires and cables gets blurred at about gage 8. Gage sizes are in increments of 2.
The second way wire size is specified is by the area of the wire’s conductor cross-section, expressed in square millimeters (mm2).
The table below compares SAE wire gages with corresponding metric sizes; it also shows the relationship between electrical resistance and wire size, expressed in ohms per 1,000 feet. The larger the wire size, the less is the resistance; the less the resistance, the greater is the maximum possible current flow.
