Course
Overview
This course is
predominantly meant for Architectural and Civil Engineering students.
It covers the fundamental
electrical circuits and related concepts without the use of Laplace Transforms.
The topics covered are also
typical FE exam topics.
Occasional
references to the NEC (of the NFPA) and NESC will be given when appropriate.
This course is a prerequisite for AREN 4570
Building Electrical Systems Design.
Below is a set of examples that shows what
can happen when there is no
NEC (National Electrical Code) and/or NESC
(National Electrical Safety Code)
Scary to say the least.


Compare that to
a group of components meeting NEMA standards and are wired/installed per the
NEC.

Lecture material
Ø There
is only enough class time to lecture just the core points.
ü So it stands to
reason that you read the material before coming to lecture and study it
thoroughly afterwards.
ü I will
predominantly (but not always) lecture from the text books.
ü I therefore urge
you to bring your text books to the lectures so you can make notes in them as
needed.
•
During Lectures
Ø I very much
encourage questions. The only dumb question is the one not asked.
ü If question are
not enough “on point” or the answers become too timeconsuming, I may hold off the
answers until office hours.
•
Homework Assignments
Ø Approximately one HW assignment per week.
ü You will scan your HW and drop it into the drop box on D2L prior
to the due date/time.
ü Late HW receives zero credit. No exceptions.
ü Make sure you do and turn in ALL HW assignments.
•
Exams
Ø Three 50 minute midterm exams
Ø A 2.5 hr. final exam
•
The Final
grade is computed as follows:
Ø Each of three midterm exams: 15%
Ø Final exam: 25%
Ø (Almost) daily quizzes: 15% (I will drop the lowest five
scores)
Ø HW: 15% (I will drop the lowest score)

Ø This will be on D2L
Ø It will be used for HW assignments, announcements, calendar,
exam dates, etc.
•
Some final comments
Ø I recognize that the amount of material is very
large.
Ø Therefore by necessity some material will only
be covered “on the surface”.
Ø It is impossible for you to become an expert at
it in a short semester.
Ø So it is my goal to introduce the material to a
level so that later, when you need to apply it, you will have enough background
and will not be afraid to open a book and study the different aspects in
detail.
Ø On occasion I will present some “hard core”
examples from my career as a licensed professional engineer in the State of
Colorado.
ü The United States Uniform Building Code, of
which the NEC is a subset, is a very well developed code. During my career I
have seen many examples that make me thankful for having this code to adhere
to.
ü I have also seen the loss of life that was a
direct result of the code not being applied or when there simply is no code.

Back in the seventies, the
wife of one of my best friends was electrocuted when touching the metal casing
of a simple cooling fan, that was pluggedin (to an ungrounded electrical
system) but was not running. The hot wire had come loose and touched the metal
casing. If this would have been a grounded system, the metal casing would have
been connected to the ground wire resulting in an immediate short circuit current
that would have blown the fuse/breaker. For this ungrounded system there was no
current return path until she touched the frame and her body and the ground she
was standing on became the return path for the current to find its way back to
the power supply. This current instantaneously killed her. A current of 50
milliAmps at 120VAC can stop a beating heart.

Last but
for sure not least
Ø If you qualify for accommodations because of a disability,
please submit to me a letter from Disability Services in a timely manner so
that your needs may be addressed.
ü Disability Services
determines accommodations based on documented disabilities. (3034928671,
Willard 322)
Ø Every effort will be made to reasonably and fairly deal with
students who have serious religious observances that conflict with scheduled
exams, assignments, etc.
ü Please notify me well in advance, so that there is time to
make adequate arrangements.
ü The Boulder campus policy can be read at http://www.colorado.edu/policies/fac_relig.html
Ø All students will be expected to comply with the Boulder
campus honor code.
ü This honor code can be viewed at http://www.colorado.edu/academics/honorcode/
Ø Students and faculty each have responsibility for
maintaining an appropriate learning environment.
ü Those who fail to adhere to such behavioral standards may be
subject to discipline.
ü Professional courtesy and sensitivity are especially
important with respect to individuals and topics dealing with differences of
race, culture, religion, politics, sexual orientation, gender, gender variance,
and nationalities.
