Course 1 – Electrical Schematics
Prerequisites: This lesson is designed so that no prior knowledge is required.
Description: This lesson shows and explains how to read and interpret the symbols on an electrical schematic the function of the input, logic, and output elements of a control circuit. This lesson identifies devices that are typically used as these elements, and presents their schematic symbols. This lesson also describes the steps for interpreting the relationships among the input, logic, and output components of an electrical schematic.
- Explain the function of the input, logic, and output element of a control circuit
- Identify the symbol for various manually operated input devices, and identify symbols for various process actuated input devices and state how they are used
- Identify the symbol for a relay and the associated contacts
- Identify various logic symbols, the symbol for a motor starter, and various output symbols and state how they are used
- Describe the layout of a typical electrical schematic and describe various conventions for labeling schematics
- Interpret an electrical schematic and know how to state the functions of its various devices
Course 2 – Electrical Diagrams
Prerequisites: This lesson is designed for participants familiar with schematic diagrams and basic electrical terminology.
Description: This lesson presents information about three types of electrical diagrams: building diagrams, single-line diagrams, and wiring diagrams. This lesson explains how to identify components, equipment, wire and cables on these diagrams how to relate the diagrams to the installed hardware and how to use diagrams for maintenance and troubleshooting problems.
- Explain the purpose of drawings and types of drawings
- Describe the layouts of the diagrams and know how to make drawing revisions, and describe the floor plan and elevation view diagrams
- Identify components, cables and conduits, and the cable chart in a building electrical diagram
- Identify voltage conventions, symbology, loads and isolation breakers in a single-line diagram
- Identify components, terminal conventions, wiring conventions, and bundles in a wiring diagram
- Relate a wiring diagram to actual hardware and actual wires, and troubleshoot a circuit using this type of diagram
