The invention discloses an electrical visual mounting plate. A required electrical component and a connecting harness on the mounting plate are determined according to an actual mounting requirement; component information and corresponding connecting harness information are drawn in proportion according to the shape of the component and a relative mounting position, and the component information and the corresponding connecting harness information form a complete electrical mounting drawing; in the drawn component information and the corresponding connecting harness information, sequential number marks in an assembly order are also included. The component information can be reflected to the mounting plate, the mounting and the layout are simple, the operation is specified, the mounting plate is assembled according to standards, simple in structure, and convenient to combine, the efficiency is improved, mounting and inspection without drawings can be realized, and the assembly speed is remarkably increased.
