"The term stray voltage describes a special case of voltage developed on the grounded-neutral system of a farm and is defined as 10 volts (measured as the root-mean-square value of 50 or 60 Hz alternating voltage, Vrms) between two points that can be contacted simultaneously by an animal (animal contact voltage). The grounding and neutral systems on a farm or in a home wiring system should be properly bonded to ensure electrical safety. As a result, some level of voltage between the grounded-neutral system and the earth (neutral-to-earth voltage) [NEV] is always present as a normal consequence of the operation of properly installed electrical equipment. The term stray voltage is often applied incorrectly to other electrical phenomena such as electric fields, magnetic fields, electric current flowing in the earth (earth currents), or electric current flowing on a grounding conductor (ground currents). Electric currents flowing in the earth or on grounded metal objects will affect animals only if sufficient animal contact voltage is developed."
