I have an excellent stray voltage story if you are interested. You may contact me at my office, 702-295-6747 or cell 702-496-1925. The case is where a Utility Grounding Electrode failed due to corrosion, resulting in an open, the current path then re-established itself through the Neutral Conductor overhead messenger cable to the Service Equipment in the Church building we were upgrading the Service in. The result was that even though we were locked and tagged and checked for absence of voltage, still unknown to us, the neutral load from the entire neighborhood was present in the 600 Amp Service equipment main grounding electrode. When this grounding electrode conductor was loosened and attempted to be lifted, the welding effect was experienced by the apprentice. An amperage meter was applied to the 4/0 grounding electrode conductor and it read 315 Amperes at 120V. The Apprentice was wearing proper PPE and no injury was sustained
