Isometric Diagram - Shows the outline of a ship, airplane, or piece of equipment. This diagram shows the components and the cable runs between the components. This diagram is used to locate components in a system.
Block Diagram - Shows the components in block form. Block diagrams are used in conjunction with text material. They are used to present a general description of a system and its functions.
Single-Line Diagram - Used for essentially the same purpose as the block diagram-to show the basic functions of a circuit.
Schematic Diagram - Shows, through graphic symbols, the electrical connections and functions of a specific circuit arrangement. It is used to trace the circuit without regard to the physical size, shape, or location of the component devices or parts. A schematic diagram shows the overall operation of a system. It is used during troubleshooting to identify possible circuit malfunction locations.
Wiring Diagram - Is a detailed diagram of each circuit installation showing all wiring, connectors, terminal boards, and the electrical or electronic components of the circuit. It also identifies the wire-by- wire numbers or color coding. This diagram must be used in conjunction with a schematic diagram to troubleshoot a system in order to find the test point for voltage and resistance checks.
Terminal Diagram - Is used in connecting wiring to terminal boards, relays, switches, and other
components of a circuit.
Safety - All individuals are responsible for understanding and complying with safety standards and regulations established to prevent injury to themselves and others and damage to property and equipment.
Having safe working habits and adhering to safety precautions protects YOU and YOUR SHIPMATES. Follow safety precautions to the letter. DO NOT TAKE CHANCES. Carelessness could cost you your life.
