Course Descriptions
During the course the students will be required
to interact with K-12 school per sonnel and other
education stakeholders in an interview format.
They will then use cur rent educational literature
available in libraries to do research on selected
issues brought up during their interviews. This
course also requires each student to devel op a
portfolio demonstrating that he/she is fully aware
of professional issues and responsibilities.

This course is a study of electric motor theory
and operation. Electromechanical principles of
motor operation are examined in detail. Singlephase
AC Motor types include the Shaded-Pole,
Split-Phase, and Capacitor-Start motor. Three-
Phase motors applications. Motors are selected
for spe cifi c applications and motor protection is
selected following NEC regulations. Emphasis
is placed on trouble shooting, on-sight preventative
maintenance, testing, repair, and replacement
of electric motors. Prerequisite: ELT 111.
ELT 103 Residential Controls

3 Hrs/Wk (1 Hr. Lecture 2 Hrs. Lab) *15 wks
This course is a study of the functioning of electrical
devices that are primarily used for manual
switching of circuits such as piloted single-pole
switches, Eagle three-way switches, and fourway
switches. Empha sis is placed on methods of
wiring these devices into a wiring system following
NEC procedures and interpreting blueprints and
schematics. Applications include selecting proper
size and type of electrical devices and cables for
a particular application. Students will convert
electrical plans into physical installations.
ELT 104 Blueprint Reading and Estimation
2 Credits (2 Lecture 0 Lab 0 Shop)
2 Hrs/Wk (2 Hrs. Lecture) *15 wks
This course is a study of electrical prints and electrical
estimation. Students will examine residential,
commercial, and industrial blue prints in conjunction
with regulation that apply from the latest version of
the National Electrical Code. Emphasis is placed
on examining these prints for the purpose of cost
analysis and material ordering.
ELT 105 Commercial Wiring and
Transformers
2 Credits (1 Lecture 1 Lab 0 Shop)
3 Hrs/Wk (1 Hr. Lecture 2 Hrs. Lab) *15 wks
This course is a study of transformers, associated
commercial/industrial wiring, and applicable
National Electrical Code (NEC) articles.
Emphasis will be placed on practi cal applications
and study of single and three phase connections,
polarity testing, use of test equipment
to determine shorts, grounds, and opens, transformer
types, and code requirements for transformer
installa tions. Prerequisite: ELT 111.
ELT 107 Industrial Motor Controls
2 Credits (1 Lecture 1 Lab 0 Shop)
3 Hrs/Wk (1 Hr. Lecture 2 Hrs. Lab) *15 wks
This course is a study of electrical motor controls.
Students select I.E.C. and NEMA magnetic
starters and overloads to control and protect motors
in conjunction with Arti cle 430 of the NEC.
Input devices include push buttons and selector
switches. Control devices include motor starters,
On-delay timers, and Off-delay timers. Typical
circuits include Stop/Start, Jog, Sequence,
Interlock, and Time-control. Particular emphasis
is placed on ladder diagrams, designing and
wiring control circuits. Prerequisite: ELT 111.
ELT 108 Basic Electronics
2 Credits (1 Lecture 1 Lab 0 Shop)
3 Hrs/Wk (1 Hr. Lecture 2 Hrs. Lab) *15 wks
This course is designed to serve as an introduction
to active electronic devices. Satisfactory
completion will help satisfy state of Maine electricians
licensing requirements. The student will
review major DC and AC concepts that will be
needed for topics to be covered in this course.
Emphasis will be placed on super position, Norton,
and Thevenin’s theorems used in analyzing
and simplifying electronic circuits. Particular emphasis
will be placed on semiconductor theory,
rectifi cation, filters, limiters, clampers, transistor
current sources and switches. The course will
provide a foundation for future studies in the
electrical and electronics areas. Pre requisite:
ELT 111.
ELT 109 National Electrical Code I
2 Credits (1 Lecture 1 Lab 0 Shop)
3 Hrs/Wk (1 Hr. Lecture 2 Hrs. Lab) *15 wks
This course is a study of the first half of the latest
National Electrical Code, NEPA 70. It offers
electricians an understanding of how the NEC
is organized and provides informa tion on proper
electrical installations. Stu dents will review and
research code rules pertaining to chapters 1
through 4. This course can be used as the code
requirement to sit for the Electrician’s Exam.
ELT 111 Electricity I
4 Credits (3 Lecture 1 Lab 0 Shop)
5 Hrs/Wk (3 Hrs. Lecture 2 Hrs. Lab ) *15 wks
This is the student’s first course in electron ics
and covers the concepts of mass, work, and
energy. Atomic structure and units of electrical
charge are covered as they apply to D.C. circuits.
Necessary test equipment including voltmeters,
ammeters, ohmme ters, and oscilloscopes will
be covered in this unit. Particular emphasis is
placed on Ohm’s Law, Kirchoff’s voltage and
current laws, series, parallel, series parallel circuits,
magnetism, and basic DC ammeter and
voltmeter design. The student will learn advanced
techniques such as Super position, Norton,
Thevenin, and Millman’s theorems used in
trouble-shooting complex circuits and networks.
