Neutral-To-Earth VoltageSafety tips and much more...
Stray voltage occurs when electricity “leaks” from the black wire directly to the white or ground wires before passing through the device to be powered. These leaks produce only small amounts of electricity. Direct contact between the white and black wires would “short” the system and blow a fuse or circuit breaker.
Stray voltage can result from arcing at equipment connections, frayed insulation and other mechanical problems. In addition, multiple grounds that are not interconnected can create ground currents capable of shocking livestock. Leaks and non-connected ground systems create electric charges in the earth that aren’t normal when an electric system is operating properly.
When these ground-based currents are present, animals or persons that contact well-grounded equipment-such as metal stanchions or metal fence posts-will receive a shock as the electricity passes through their bodies. These N-E voltages, through rare, exist on all devices and are most common on farm feeding and milking equipment.
