For terminal wire processing, the wire must have sufficient strength. If the strength is not enough, it is easy to break due to some external forces, such as strong wind, icing, or improper handling during repairs; if you choose a wire with a thin section , It is easy to cause overheating when using overload current, which will damage the protective insulation layer, which will seriously cause the circuit to catch fire; and the selected wire must not have excessive voltage loss.
Therefore, when processing the terminal wire, we are selecting the wire, which needs to be selected according to your circuit situation. If you choose a low voltage, choose the thickness of the wire according to its heat generation, and then test its voltage loss and strength. If it is high voltage, then the wire needs to be selected according to its current situation, followed by measuring its heat generation and voltage loss.
