Module 4A: Wiring Circuits (Core)

Suggested time: 15 - 25 hours

Level: Intermediate

Prerequisite: Module 3A

Foundational Objectives

To use appropriate terminology for electricity or electronics in context.
To read, understand and interpret schematic diagrams and other technical documents.
To be knowledgeable about the various principles and characteristics of electrical and electronics.

Common Essential Learnings Foundational Objectives

To understand, explain and apply the principles of basic electric circuitry. (COM, CCT)
To follow code rules and safety practices required in all activities. (IL)
To apply the principles of electrical circuitry. (TL)

Learning Objectives	Notes
AC POWER SYSTEMS
4.1 To understand and compare a neutral wire, a hot wire and a ground wire. (COM, CCT)	Review different AC circuits. Hook up a simple circuit and with the help of multimeter explain why a ground wire is being used. Research the characteristics of lightning and explain why lightning arresters are used.
4.2 To understand the 120/240 volt three-wire systems. (COM, NUM)	Draw a schematic diagram and label all wires in the three-wire system. Observe a three-wire system, as a demonstration for the students. With the help of a multimeter, have students check different voltages and explain their answers.
	CIRCUITS
4.3 To draw a simple circuit.	Draw a simple circuit and label all the parts (load, source, etc.)
4.4 To define a short circuit. (COM)	Students should look at examples of equipment that has been short-circuited and discuss what they see.
4.5 To draw schematic and wiring diagrams for different electrical circuits. (IL)	Have students examine different circuits. Have them draw and label the schematic and wiring diagrams (e.g., single pole switch, three-way switch, four-way switch and duplex receptacles).
ELECTRICAL CIRCUIT INSTALLATION
4.6 To list electrical code rules that apply to a given situation. (COM, CCT)	Give students several examples of specific circuits and have them: identify the code rules that pertain to each circuit determine the tools that will be needed for certain jobs determine which electrical components will be needed.
4.7 To install a branch circuit using the proper hand tools and electrical components required. (CCT)	Review the types of screwdrivers and pliers required to complete the task. Students must follow the most recent federal and provincial resources defining electrical codes that are published every four years.
4.8 To assemble different circuits given the required components. (IL)	Have students install the following circuits: duplex receptacles single pole switch controlling a light three-way switches controlling a light four-way switches controlling a light. Have students wire any combination of the above circuits.
