12-14 July: Earthing and Bonding

Proper grounding and bonding of electrical equipment helps 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.
