Schematic Diagram Design • The schematic diagram resembles a ladder in that it is made up of two vertical lines

representing the incoming electrical sources.• The electrical source is electrical energy being supplied to equipment.• The schematic wiring diagram uses symbols to represent electrical components in the

system.
