Low voltage is an
electrical engineering term that broadly identifies safety considerations of an
electricity supply system based on the
voltage used. While different definitions exist for the exact voltage range covered by "low voltage", the most commonly used ones include "mains voltage". "Low voltage" is characterised by carrying a substantial risk of electric shock, but only a minor risk of
electric arcs through air. "Low voltage" is distinguished from:
Extra low voltage – which carries a much reduced risk of electric shock
High voltage – where electrical arcing is a substantial additional risk.
