About This Video
Step voltages — large differences in electrical potential across a short distance on the ground surface — are a leading cause of electrocution deaths during lightning storms and near downed power lines. David Stockin explains the physics of step voltage, how it kills, and the grounding and equipotential bonding strategies that can prevent these tragedies.
