Grounding and Bonding – Canadian Electrical Code Section 10

Grounding and Bonding Training for Canadian Electrical Code Section 10 explains grounding electrodes, bonding conductors, equipment bonding, and fault-current return paths. Learn grounding system design, bonding requirements, and grounding system testing for compliant electrical installations.

12-hour, two-day instructor-led course teaches electrical engineers, electricians, technicians and maintenance professionals how to design, install, test and inspect grounding and bonding systems. The course focuses on Section 10 of the Canadian Electrical Code (CEC), with supporting references to NEC Article 250 and IEEE grounding standards. 

Why Grounding and Bonding Training Matters

Poor grounding and bonding is a leading cause of electrical fires, shock injuries, equipment damage, nuisance tripping and failed inspections. Many installations meet the wording of the code but still don’t give fault current an effective, low-impedance path back to its source.

Grounding systems are getting more complex. Solar PV, battery energy storage, EV charging, standby generation and sensitive electronics all bring grounding challenges that older practice never had to address. Workers need to know what the code requires and why it requires it.

Grounding systems also degrade over time. Corroded connections, damaged conductors and rising electrode resistance stay hidden until a fault or lightning strike exposes them. Regular testing and inspection keep a grounding system doing its job.

Our 12-hour instructor-led Grounding and Bonding Training teaches electrical grounding systems, bonding conductors, grounding electrodes, and fault-current return paths used in safe power installations. The course also examines grounding requirements defined in the Canadian Electrical Code and how they apply in real electrical systems. Participants learn how grounding electrodes, bonding conductors, ground-fault protection and effective fault-current return paths protect personnel, equipment and electrical installations.

Through practical engineering examples and real-world applications, this live training course covers grounding electrode design, soil resistivity and ground resistance testing, bonding conductor sizing, resistance-grounded systems, and touch and step voltage safety. Participants also examine grounding requirements for industrial, commercial, institutional and utility facilities, including renewable energy installations, battery energy storage systems (BESS), data centres and lightning protection. The emphasis is on applying electrical code requirements, identifying grounding deficiencies and improving electrical safety and system reliability.

 

Course Highlights

  • Section 10 of the 2027 CEC applied to real installations, with NEC Article 250 cross-references
  • Electrode systems, soil resistivity and resistance grounding (HRG and LRG)
  • Bonding conductor sizing, fault return paths, and touch and step voltage safety
  • Grounding testing procedures, including which tests can be done energized and which need a shutdown
  • Grounding for PV, BESS, EV charging, data centres, SCADA and lightning protection

 

Learning Outcomes

By the end of this course, you will be able to:

  • Explain the purpose of grounding and bonding, and how each one protects people, equipment and system operation
  • Apply the grounding and bonding requirements in Section 10 of the 2027 CEC to service, feeder and branch circuit installations
  • Select and install grounding electrodes, and work out how soil resistivity affects electrode resistance
  • Compare solidly grounded, ungrounded, high resistance and low resistance grounded systems, and choose the right method for an application
  • Ground separately derived systems, generators, transfer switches and UPS systems correctly
  • Size bonding conductors and confirm an effective ground fault return path
  • Assess touch voltage, step voltage and ground potential rise hazards
  • Carry out soil resistivity, fall of potential, clamp-on and continuity tests, and interpret the results
  • Apply grounding practices for PV, BESS, EV charging, data centres, SCADA and EMI control
  • Design lightning and surge protection grounding, and inspect existing grounding systems for deficiencies

 

Course Approach

The course is vendor-neutral and based on worked examples. Each module ties code requirements to field tasks, case studies of failures, and calculations you can use on the job.
