Voltage Drop Course Syllabus

Instructor:
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.

Text Books:
There are no textbooks required for this course.  Material is included in the illustrations that accompany the questions.

Description:
This is a four 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 1200 seconds (20 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 updates the student's record for continuing education in the State of Washington L and I database for Washington persons 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. 

Goals:
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.
