Grounding and Bonding (GB)

Open Enrollment and Onsite Availability

Grounding and bonding systems ensure that electrical systems are safe from electric shock and fires by limiting the voltage imposed by lightning, line surges, or unintentional contact with higher-voltage lines as well as a ground-fault (phase-to-ground fault). Article 250 of the National Electric Code identifies grounding and bonding system installation methods. A properly installed grounding or bonding system for shielding, EMI, static and lightning protection can help prevent cable failures, equipment damage and power quality problems. These systems are also important for personnel protection and compliance with OSHA 1910.301-.308, and .331-.335.

Who Should Attend
This course is intended for technicians, electricians, engineers and inspectors responsible for the installation, maintenance, troubleshooting and repair of grounding and bonding systems greater than 50 volts.

Learning Objectives

  • Interpret applicable NEC article 100 and 250 definitions
  • Identify safety hazards created by ineffective grounding systems
  • Perform 2, 3 and 4 point earth resistivity tests and interpret results
  • Tie into a grounding grid
  • Explain equipment utilization for lightning suppression, grounding and bonding systems
  • Establish correct troubleshooting and counter EMF and noise techniques
  • Understand the effect of connecting grounded and bonded systems


This course requires knowledge of the National Electrical Code and basic electrical theory.
