Standard for conductor connection of distribution cabinet

According to the standards for wiring connection of distribution cabinet, the minimum cross-sectional area of insulated conductor of distribution board shall be 1.0 mm?. for low-level electronic circuits, it is allowed to select conductors with cross-sectional area less than 1.0 mm? (but it shall not be less than the requirements of the electronic equipment manufacturer for the installation of conductor cross-section). When the cross-sectional area is not more than 8mm?, the tortuous radius should be greater than 3 times of its outer diameter.
The transition conductor of the movable part such as the panel of the distribution board shall be windable. The insulation of connecting conductor shall be resistant to moisture, mildew and flame retardation, and its insulation voltage level shall be greater than or equal to 250V when the line operating voltage is less than or equal to 100V, and the insulation voltage grade shall be greater than or equal to 250V when the line operating voltage is greater than 100V and less than or equal to 450V
The insulation voltage level shall be greater than or equal to 500V. The conductor shall be connected to the specified terminal in strict accordance with the drawings. The wiring should be placed orderly, clear and beautiful, with excellent insulation and no damage. External wiring shall not cause rated stress inside the appliance. Wiring shall be carried out according to the terminal mark.
The minimum wire diameter of the connecting power indicator light is 1.5mm2. The minimum single circuit path to the circuit breaker and leakage switch is 1.5mm2. The minimum single main circuit path is 1.5mm2. The minimum wire diameter of the switch jumper line is 2.5mm2. The minimum wire diameter into the transformer primary winding is 1.5mm2 The minimum wire diameter from the panel control circuit to the bottom plate is 1mm2.
