I am struggling understanding an item that I see happening every so often and few instances here lately, it involves the voltage potential on the ground of a 120 volt circuit. My question is how is there voltage on the ground circuit of a 120 volt system? The ground is used for incident energy (i.e. arc flash, lightening etc) not normal voltage or current path. The circuit path should be hot leg through the device returning on the neutral leg. Could someone please explain the logic that it is okay to have the voltage on the ground during normal operation.
