(H) explain the purpose and required locations of ground fault circuit interrupters; (I) describe single-phase service connections; and (J) describe both wye-phase and delta-connected three-phase services Unit 12: Fuses and Circuit Breakers 30 Periods (11) The student knows the practical application of fuses and circuit breakers. The 1,350 Minutes student is expected to: Students will learn how fuses, circuit breakers, (A) explain the necessity of overcurrent protection devices in electrical and ground fault circuit interrupters (GFCI) circuits; provide overcurrent protection in electrical (B) define the terms associated with fuses and circuit breakers; circuits. Students understand overcurrent (C) describe the operation of a circuit breaker; protection overview, disconnect switch (D) select the most suitable overcurrent device for the application; coordination, fuses and circuit breakers, dual (E) describe the operation of single-element and fuses; element time delay fuse, non time delay fuses, (F) explain how ground fault circuit interrupters can save lives; cartridge fuses, plug fuses, and testing fuses. (G) calculate short circuit currents; and Students will also learn about circuit breakers, (H) describe troubleshooting and maintenance techniques for overcurrent thermal magnetic circuit breakers, circuit breaker devices coordination, HACR circuit breakers, and low voltage lighting systems. Students will use technical vocabulary when describing the functionality of single-element and time-delay fuses as well as with thermal and magnetic circuit breakers. Students will focus on understanding, interpreting, analyzing and knowing how to correctly use electrical formulas, units of measure, mathematics concepts, and science principles in order to solve problems. Unit 13: Principles of Lighting 30 Periods (13) The student learns the basic principles of human vision and the 1,350 Minutes characteristics of light. The student is expected to: Students will differentiate between different (A) explain how the human eye works; types of electrical lighting fixtures including (B) describe the characteristics of lamps, surface mounted, recessed, suspended (C) recognize the different kinds of lamps and explain the advantages and and track-mounted. Students will compare and disadvantages of each type, including incandescent, halogen, fluorescent, contrast the different types of lamps consumers and high-intensity discharge;
