Module 1:

Grounding Low Voltage Power Systems

This is not your standard course within the industry that teaches you just how to comply with the NEC. It goes beyond the code minimums. Read on!!

This course is co-sponsored by I.E.E.E. ( The Institute of Electrical and Electronics Engineers, Inc.) with discounts available for I.E.E.E. members.

The course will cover general and detailed theory and principles used for the design of power system and equipment in systems up to 1,000-V. It is structured to cover all areas of concern for practicing electricians and industrial, commercial, and engineers. It will also point out major technical errors in Soares latest grounding book.

Most courses on this topic only address the "how to ground" but omit the "why". Consequently, designers and installers do not have the requisite knowledge to know how to handle unique situations and how to correctly utilize lightning and surge protection equipment connected to power systems. This course will focus on the theory governing grounding system design and construction and basic computations necessary to properly interpret NEC requirements and when you must go beyond the minimum NEC requirements to provide a safe system.

This course will draw into the curriculum, design and theoretical principles, published within industry and national standards and decades of I.E.E.E. papers written on the subject. It will also be focused on the information the instructor has relied upon during his professional career as a designer, construction inspector, consultant, and instructor.

Instructor: Charles Pratt, P.E.

  • Practicing professional engineer since 1971.
  • Life member of various I.E.E.E. power, industry, and EMC societies
  • Member of the Lightning Protection Institute.
  • Member of N.F.P.A.
  • Previous instructor for Army Corps of Engineers in the technical areas of power, surge protection, and lightning protection grounding system design
  • Design engineer for virtually all types of industrial , commercial , and utility electrical systems.
  • Member of IAEI, International Association of Electrical Inspectors

Why is this course unique?

  • Covers commercial and industrial grounding systems and protection from effects of ground faults that can present adverse shock hazards to humans.
  • Proper interpretation of information in Soares Grounding book including information within this book that should not be used for design. (Examples: Several tables in Chapter 22 and the statement that "sharp bends in conductors increases impedance")
  • Will remove much of the "mystique" and "black magic" commonly associated with grounding for safety and low voltage surge protection including the mystique of the NEC 25-ohm ground These topics should not be a mystery!
  • Not a software course. Understanding principles is more important.
  • Taught by an instructor with decades of experience separating fact from fiction and "sales pitches.
  • Reveals technical errors promulgated in various books and literature including the NEC. (Example: Table 250.122 is inadequate for day to day use.)
  •  Provides students with theory and lab demonstrations of voltage profiles around common grounding electrodes to support the theory
  • Covers the electrical theory, system analysis, and physics which form the basis for grounding system design. Answers many of the "Whys" that most grounding practicioners encounter.
  • Grounding electrode and array performance under normal power system frequencies and fast transients .
  • Grounding of systems and equipment for compliance with the NEC and beyond
  • Class sizes are kept small to optimize your personal learning experience
  • Grounding system testing and calculations will be covered. Handy charts for computing the resistance of various grounding electrode configurations along with an equipment grounding conductor fusing chart are included. These cannot be found in other literature.
  • Papers explaining why special considerations need be made for paralleled conductor runs, power circuit breakers, and other confusing topics covered in the course.
  • Hands-on experience in seeing and measuring actual grounding system conductor and electrode peformance.
  • Design of grounding and bonding systems for NEC compliance
  • Design tips provided to minimize system redesign
  • Information exceeds that of any other similar course on the market

Course Structure

The depth of the material is geared for electricians and graduate electrical engineers . Standards such as the NEC, I.E.E.E., and other important standards are addressed. The IAEI book "Soares Grounding & Bonding-NEC 2020" will be used to drive the curriculum for this course.

The course is held in conjunction with other grounding course modules. Each module can be taken separately, however maximum benefit will come from taking all modules at one time or in order. More details of the various topics in each module are contained in the course information links.

Time will provided to work through computations for grounding electrode, equipment grounding, and surge protection systems designed to demonstrate practical use of the information covered in the course.

Knowledge Base

The student will benefit from this course if they are comfortable in the use of basic concepts, formulas, and methods used to analyze electrical circuits. Although these concepts, methods, and formulas are covered during the lectures, it is assumed that the student is familiar with them and can apply them prior to attendance. The following is a list of those important to this goal.  There are many videos available on the internet on these concepts if you need a refresher.

Ohm's Law

Resistance, inductance, capacitance, and reactance

Combining series and parallel resistors, inductors, and capacitors and use of voltage divider formulas

Thevenin equivalent circuit reduction

Course Materials

The student will receive an extensive workbook that exceeds the quality of training manuals of most courses of this type. Workbook pages contain a single lecture slide and appropriate comments by the instructor designed to minimize note taking by the student and to provide a more useful future reference. (View sample pages)

In addition, a copy of the IAEI book "Soares Grounding & Bonding-NEC 2017, 13th Edition" can be provided for those attendees requiring a copy. For maximum benefit from the course attendees are encouraged to order their own copy of this book from IAEI prior to the course for study. Doing so will give the attendee time to read the material and develop any questions they may have that the wish to be addressed during the class.


The schedule for each course varies. See the published schedule for the specific course listed.

Continuing Education Credits

CEU's or PDH's will be provided for each course  module through the I.E.E.E. Education Program for those students needing professional continuing education credits. The credits vary for each module attended and are tabulated in each course registration form.

Price:  $950.00 (US)

(There is a 10% discount available for I.E.E.E. members registering at any time in addition to any other discounts offered. See registration form for early registration and other discounts. )

Dates and Locations

See "Training" webpage.

Participant slots are limited to 16 to maximize student involvement in lab demonstrations.
