What exactly needs to be grounded in a house, and how is it done? That’s what this video explains as it demonstrates how to install a low-resistance panel-to-earth grounding system. Other surge and lightning protection devices are also discussed, and tips on testing systems for functionality and safety are included. A viewable/printable instructor’s guide is available online. Correlates to the National Center for Construction Education and Research standards.
