Fast clearing of faults, made possible by good grounding, improves the overall safety and reliability of an electrical system. This course will provide the basic principles of grounding a power supply network to ensure safety of personnel and equipment. Understanding these principles will provide the correct tools to design a grounding system applicable to utility networks and industrial plant distribution. This course covers the basic procedures in working safely on medium and high voltage systems.

CEUs are granted by either "North Idaho College", "Gonzaga University", "IEEE" or the Engineering Institute of Canada. One CEU is equivalent to 10 professional development hours of instruction. The following course earns 1.4 CEUs. COURSE BENEFITS It has been determined that over 70 per cent of all electrical problems in industrial, commercial and institutional power systems are due to poor grounding and wiring errors. Without proper grounding, sensitive electronic equipment is subjected to destruction of data, erratic equipment operation, and catastrophic damage. This electrical grounding seminar will give participants a comprehensive understanding of practical applications of proper grounding and wiring practices. Increase Your Knowledge · Focus on specific electrical grounding problems and consequences relating to fires, safety of personnel, and damage to equipment · Participate in discussion of electrical grounding problems and how to overcome or avoid them · Gain a firm foundation of knowledge for your next project involving electrical grounding · Develop your knowledge of theory and practice Learn About · The requirements of the National Electrical, CEC in Canada and NOM 001 in Mexico. · Specific grounding problems, installations and code requirements · Testing procedures for residential, industrial, commercial and institutional electric power grounding systems · Practical solutions to grounding problems After Attending, You Will · Work more safely and efficiently · Have a better understanding of Article 250 in the 2005 N.E.C.® · Be more aware of the benefits of good grounding systems · Be better prepared to design your next grounding system Who Should Attend This electrical grounding course is a must for electrical engineers, design engineers, electrical engineering managers, project managers, power quality specialists, maintenance managers, consultants and technologists responsible for the design, construction, installation, inspection, operation, or maintenance of electrical systems, designers, contractors, and electrical technicians, inspectors, safety personnel and other employees responsible for the operation and maintenance of electrical grounding systems in a commercial, industrial, institutional or utility setting. Effects of Poor Grounding Without good grounding, sensitive electronic equipment is subjected to destruction of data, erratic equipment operation, and catastrophic damage. Inductive effects of lighting including transients, wiring errors, and code violations cause damages estimated at about $20 billion dollars in the US and Canada each year. The economics: Loss of sales, Loss of production, Loss of work in process. The knowledge acquired in this course will enable the participant to apply correct electrical installation procedures (CEC/NEC), effective cabling and state of the art technologies available for the protection of equipment and circuits. Code violation poses the greatest hazards to human life. Other considerations: Sometimes a system shut-down can cause a telecommunications company thousands of dollars per hour. To a petrochemical company, an unplanned shut down can cost millions of dollars. With the practical application of the Electrical Code (CEC) and electrical grounding practices, which minimizes errors and loss of equipment, the cost of the course will be amortized many times over. Other considerations are Warranties and Guarantees. For insurance validation, these warranties/guarantees are based on compliance with the Electrical Code (learned in this course).
