Why is there not a hole in the wiring board
The answer is that the positive current requires at least two lines to form a circuit to supply power to the electrical equipment, so the plug is at least two ends, and the socket and wiring board are also two or three holes.Generally, there are clear regulations on whether the plug is two or three ends.
