Gerald Newton is a licensed
electrical Administrator in Alaska in the Unlimited Commercial, Inside
Communications, and Residential Wiring categories. He also is a
licensed journeyman electrician in the States of Alaska and Washington.
He graduated from the William Paterson College in 1975 with a degree
in Mathematics. He has over 40 years experience in the electrical
industry including 8 years as a State of Alaska electrical inspector
enforcing the NEC and the NESC, and 20 years as a construction
electrician performing electrical construction work. Over the last 20
years he has taught electrical courses and for the past 15 years has
maintained and operated electrician.com or electrician2.com.
electrician.com was the very the first electrical site on
the Internet starting in July of 1995. He created the very first
approved online electrical continuing education courses for electricians
and electrical administrators in the USA delivered over
the Internet in January of 1999.
There are no textbooks
required for this course. Material is included in the
illustrations that accompany the questions.
This is an eight hour
course on Voltage Drop and Calculations. The first 10
tests for this course consists of 10 questions each for a total of 100
questions. Test 11 has only four question but they are multipart
requiring more complicated calculations. The eleven Final Tests must be taken and passed with a 70 per cent or higher
score. Each time
you submit a test the server grades, records and then sends the grade
back to the test page for the student to see.
Tests cannot be submitted for grading until after
(40 minutes of cumulative time.) The lapse time for each test is
recorded at the server and so is the time that the test was submitted.
After the recorded tests
are completed and passed a link for the notification of completion
permits the student to notify electrician2.com that they have completed
the material. The notification of completion form is automatically
emailed to electrician2.com when the submit button is clicked. After the notification is received
by email the instructor
reviews the records to ensure that the tests have been passed and the
required time taking the tests is acceptable and
payment has been made.
The instructor then sends a certificate
of completion to the student by email and sends a certificate by email and US mail for
Alaska persons. This is usually done
within 24 hours after the notification of completion is received.
Learn how to calculate voltage
drop for 2 wire DC, single phase 2 wire, 3 phase 3 wire and 4 wire
circuits where loads are balanced and not balanced. Find 3 phase circular mil area of conductors to satisfy given conditions,
maximum length for given conditions, circular mil ohms per foot, power
factor using cosines, and many other variables associated with voltage
drop. Use of Tables 8 and 9 in Chapter 9 of the NEC are covered
for finding voltage drop. The last test utilizes a voltage drop
calculator built into the test that does 8 different types of voltage
drop problems at once for comparisons including those for power factors
other than one. Segmented voltage drop is discussed as applied to
R/V Park feeders. The Neher McGrath formula is also discussed to
develop equations for finding the actual operating temperature of
conductors then finding the circular mil ohm resistance for that
temperature. This course requires students to have some background
in Algebra, Vectors, and Trigonometry. This course is mathematical
intensive, but the various mathematical subjects are reviewed for any
one that may have forgotten their math.
