电气配线原则（Electrical wiring principle） Low voltage electrical equipment - wiring principle Wiring principle In front of the plate surface wiring: manual wiring (non model, mould, wiring) should comply with the straight, neat, close to the surface, laying reasonable alignment and not loose contact easy maintenance requirements. 1, the routing channel should be as few as possible, the bottom wire in one channel, according to the main control circuit, classification, single or parallel close packed bundles should be close to the face. 2, the conductor length should be as short as possible, can be horizontal overhead crossing, such as two components coil, the connection between the main contact line, etc., in the case of a certain margin, not close to the laying surface. 3, the same plane wire should be consistent or consistent, can not cross. Horizontal crossing must be used when crossing, but must be reasonable. 4, wiring should be horizontal vertical, change direction should be vertical 90 degrees. 5, the upper and lower contacts, if not in the same vertical line, should not use slash connection. 6, the wiring and wiring terminal or line pile connection, should not pressure insulation layer, no reverse ring and exposed copper is not more than 1mm. And to achieve the same component, the same circuit of different contact wire between the same distance. 7. The connecting wires on the wiring terminals of an electric appliance component shall not be more than two. The connecting wires on each connecting terminal board shall only be allowed to connect with one. 8, wiring is strictly prohibited damage to wire core and wire insulation. 9, the conductor cross-sectional area is not the same, this will be large cross-sectional area on the lower, small section of the upper layer 10, the wiring of the main wiring (main circuit) should be done in the same level or the same vertical face. 11, if the line is simple, can not be coded casing. Color mark of wire: 1, protective wire (PE) m
