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.
