Connecting the harness
A circuit group provides the overall set of service equipment for a certain load source group, such as relay lines, switching devices, and control systems. The basic research content of traffic theory is to study the relationship between traffic, call loss, and harness capacity. Therefore, harness is an important basic concept in traffic theory.

Description
A circuit group provides the overall set of service equipment for a certain load source group, such as relay lines, switching devices, and control systems. The basic research content of traffic theory is to study the relationship between traffic, call loss, and harness capacity. Therefore, harness is an important basic concept in traffic theory.
In order to facilitate installation and maintenance, and ensure that the electrical equipment can work under the worst conditions, wires of different specifications and colors used for various electrical equipment in the entire vehicle are integrated through reasonable arrangements, and the wires are bundled with insulating materials, which is both complete and reliable.
2. Normal selection of wire cross-sectional area and color code
1) Correct selection of wire cross-sectional area
The electrical equipment on the vehicle selects the cross-sectional area of the wires used based on the magnitude of the load current. For electrical equipment that operates for a long time, 60% of the actual current carrying capacity of the wire can be selected; Electrical equipment operating for a short time can use 60% - 100% of the actual current carrying capacity of the wire.
2) Selection of wire color code
In order to facilitate identification and maintenance, the wires in the electrical harness have different colors.
For the convenience of labeling in the circuit diagram, the colors of the wires are represented by letters, and the colors represented are noted in each circuit diagram.
