Electrical expert witnesses may consult on issues regarding electrical design evaluation, electrical accidents, and electrical shock. At http://www.intelligentutility.com/, electrical engineer Donald R. Johnson writes: “Stray voltage is a much more common occurrence than the general public realizes.” Mr. Johnson specializes in evaluating stray voltage as well as high and low voltage electrical contacts.
Wikipedia describes stray voltage as “the occurrence of electrical potential between two objects that ideally should not have any voltage difference between them.”
