For general low-voltage control cabinet secondary circuits, the minimum wiring cross-sectional area of the voltage circuit is 1.5 square meters, and the minimum cross-sectional area of the current circuit is 2.5 square meters. The current circuit refers to the current signal line of the current transformer, ammeter, power factor meter, current signal line of the mutual inductance meter, etc. The current passing through is 5 amperes. In addition, the power line is yellow green red, and the zero line is blue or light blue (some are gray, because international standards also distinguish between European standards or American standards). The main circuit should have a black wire of at least 1.5 square millimeters, a red wire with an AC voltage of 1.0 square millimeters, and a blue wire with a DC voltage of 1.0 square millimeters. The color of the signal line is not required
