There is current in the ground wire of the distribution box
There will ALWAYS be current on the ground, because it's a parallel path. In most cases, the impedence of the ground return path is much higher than that on the neutral, with a corresponding much smaller current, but that is not always true. The house has 400A service so I have two main panels of 200A each. There are two electrical service lines, one for each panel and two solid copper ground lines in addition to a gang of ground wires that are part of the service lines. I also have a 20KW generator with an Automatic Transfer Switch. Run a wire from the energized slot of an outlet to an electrode driven into the ground. Now imagine starting the generator. 26 mm 2 (10 AWG) ground wire must be used, and in all other markets a 6 mm 2 must be used. Grounding is needed for electric safety and it also creates a reference point in a circuit to.
