Basic Introduction Of Automotive Wiring Harness
Nov 02, 2018

Wire harness in the automotive wiring commonly used specifications have a nominal cross-sectional area of 0.5, 0.75, 1.0, 1.5, 2.0, 2.5, 4.0, 6.0 and other square millimeters of wire (the nominal cross-sectional area commonly used in Japanese cars is 0.5, 0.85, 1.25, 2.0, 2.5, 4.0, 6.0, etc. square millimeters), Each of them has a allowable load current value, which is used for conductors of different power devices. Take the whole vehicle wiring harness as an example, the 0.5 specification line is suitable for the instrument lamp, the indicator light, the door lamp, the ceiling lamp, etc. 0.75 specification line applies to the license plate light, the front and rear small lamp, the brake lamp, etc. 1.0 specification line applies to the turning lamp, the fog lamp, etc. 1.5 specification line applies to the headlight, the horn 2.5 to 4 square millimeters of wire are required on the rail line.

This only refers to the general car, the key to see the maximum current value of the load, such as the battery of the wire, the positive power line is dedicated to the use of automotive wire, their wire diameter is relatively large, at least more than 10 square millimeters, these "Big Mac" wire will not be programmed into the main bundle.
