This question is about step potential. It refers to the voltage difference between the feet of a worker standing near an energized object. When a live object or line energizes the ground, the earth around it isn’t at a uniform voltage. Each foot sits at a slightly different ground potential depending on its distance from the source, so a potential difference can exist between the feet. If that difference is enough, current can flow through the legs from one foot to the other, posing a shock risk. This is why staying aware of footing and distances around energized equipment is crucial. Touch potential would involve the voltage difference between a hand contact with the energized object and the feet, while ground potential is the overall earth potential at a location and neutral potential is the electrical system’s neutral reference—neither of which describe the between-feet difference.
