  1. My house has a concrete slab and I cannot find evidence of a grounding rod, I think it has an "ufer" ground.

  3. Keith Newton Do they have concrete slabs? If so, they may be using a modern version of an "ufer" ground, where the ground wire is connected with the rebar.

  4. True, but the neutral center tap of the transformer, the source, is connected to earth ground.

  5. Electrons only move in a closed loop when a load is applied. This loop includes the secondary windings of the transformer. In the case of a short or an over current situation the breaker will trip. This has nothing to do with the grounding rod.

  6.  @lightweaverx4381  True enough, but my comment was intended to be applicable to residential wiring in the U.S. specifically, based on my understanding, not about electromagnetism in general.
