When installing the power supply, both input and output ends need to be connected by wire. The following points need to be considered in selecting wires.
(1) Current rating : if the current rating is insufficient, the wire temperature will be too high or even burned
(2) Voltage drop : the wire itself has impedance, when the current flows, it will cause voltage drop. If the voltage drop is too high, it will cause the voltage at the load end to be too low, which may cause the load to fail to work.
(3) Noise : it can be a problem for wires, especially when high frequency signals travel long distances, using shielded wires may help eliminate noise and EMI disruptions.
