This course begins with magnetism and electromagnetic theory followed by the principles of operation of series, shunt and compound direct current generators and motors, manual motor starters and applications of bearings used in rotating machinery. (Prerequisite: ETEC1240L or LELC1240) (Updated for 9/2011)
A study of NEC requirements as it applies to residential applications.
A study of NEC requirements as it applies to Multi-Family Units.
A study of NEC requirements as it applies to commercial and industrial applications.
This course provides the student with a solid grounding in the operation of solid state control devices including; but not limited to, diodes, rectifiers, silicon controlled rectifiers, phototransistors and LED’s. (Prerequisite: ETEC1240L or LELC1240)
This course uses computer-aided programs. The following topics will be covered: introduction to estimating concepts, computer aided electrical estimating, and developing an estimate using an electrical blueprint.
ETEC2150L Photovoltaics (3 Credits) (9/2011)
This course introduces the principles of photovoltaics; including the basics of safety, the electrical basics of solar PV systems, and how modules are designed and combined with other system components. Participants will learn how to decide upon the size, electrical and mechanical design of a PV system, as well as how to analyze and troubleshoot problems. The lab portion of the course will include hands-on installation of PV systems on mock roofs and ground mounts. This PV Entry Level course will not earn students an installer-in-training credential, but will serve as an important first step in preparing individuals to become highly skilled, qualified and experienced trades people in the PV industry. At the conclusion of the course, students will be eligible to take the examination for the NABCEP PV Entry Level Certificate of Knowledge. Students should have a basic understanding of electricity fundamentals before enrolling in this course. Credit will not be given for more than one of the following courses: ETEC2150L or LELC2150; ESTC1500L or LEST1500. (Prerequisite: ETEC 1240L or LELC1240)
