This Grounding and Bonding.Training course is founded on the NEC/CEC and is designed to give you the correct information you need to design, install and maintain effective electrical grounding systems in industrial, commercial and institutional power systems.
One of the most important AND least understood sections of the NEC/CEC is the section on Electrical Grounding.
This course will address all changes on Grounding & Bonding included in the NEC/CEC
The NEC/CEC recognizes materials other than Copper for uses as a Grounding Conductor in ten different articles of the code. It also addresses corrosion issues in new added Subrule.
There are new Sub rules on Bonding Conductors that bonds fixed equipment. Some other Sub rules have been amalgamated into a new rule. One of the most important changes has been that the new code does not favor “water Pipe” as a grounding electrode. Some other rules have been modified to require alarm indicator installation to indicate a fault on certain systems.
Some other Sections have been changed to be consistent with the rest of the code in particular the Ground Fault Circuit interrupters. Changes have been made to Station Grounding, to meet the maximum permissible Resistance of Station Grounding Electrode. Some of the requirements for driven Ground Rods were deleted, to be consistent with NEC/CEC standards.

It has been determined that more than 70 per cent of all electrical problems in industrial, commercial and institutional power systems are due to poor grounding, and bonding errors. Without proper electrical grounding and bonding, sensitive electronic equipment is subjected to destruction of data, erratic equipment operation, and catastrophic damage. This electrical grounding and bonding training course will give participants a comprehensive understanding of practical applications of proper grounding and bonding practices that will comply with the Canadian Electrical Code.

Without good grounding and bonding, sensitive electronic equipment is subjected to destruction of data, erratic equipment operation, and catastrophic damage. Allen G.W. Segall (IBM Study) determined that 88.5% of all disturbances are caused by transient overvoltage and, therefore, it is of critical importance to know the "state-of-the-art" protection technologies.
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, based on the following considerations: risk to personnel, equipment replacement cost, repairs cost, and destroyed data. The economics: Loss of sales, Loss of production, Loss of work in progress. The knowledge acquired in this course will enable the participant to apply correct electrical installation procedures according to the NEC/CEC, effective cabling and state-of-the-art technologies available for the protection of equipment and circuits. A code violation poses hazards to human life and equipment.
