Proper grounding and bonding of electrical equipment helps to ensure that the electrical equipment and systems safely remove the possibility of electric shock by limiting the voltage imposed on electrical equipment and systems from lightning, line surges, or unintentional contact with higher-voltage lines, as well as ground-fault conditions (any phase-to-ground).

Article 250 of the National Electric Code® identifies grounding and bonding system installation methods. Proper grounding and bonding is also important for personnel protection, as well as for compliance with OSHA 29 CFR 1910.304(g) Grounding.
This course focuses on the grounding and bonding requirements contained in Article 250 of NEC®. Specific topics that are addressed include, but are not limited to: definitions grounded (neutral) conductor requirements; sizing equipment grounding conductors, equipment bonding jumpers, grounding electrode conductors, and main bonding jumpers; identifying types of grounding electrodes; requirements for multiple grounding electrodes; bonding requirements for non-electrical equipment; the purpose of impedance or resistance grounding; requirements for an isolated grounding system; and grounding and bonding requirements for the line side and the load side of the service disconnecting means.
At AVO Training Institute, our base courses such as grounding electrode resistance testing and earth resistivity testing will be performed at our outdoor training yard. On-site training of this course will require the site facility to provide an adequate test area to perform the earth resistivity and earth resistance tests.
Who Should Attend
This hands-on course is intended for new or experienced electricians and technicians that install, maintain, repair or troubleshoot power and auxiliary systems. The participant should have basic knowledge of power system components.
