A line voltage system is a type of electrical power distribution system that operates at a higher voltage than a low voltage system. It is used to transmit electricity over long distances and is typically used in commercial and industrial applications. Line voltage systems typically operate at voltages of 120V, 208V, 240V, 277V, and 480V. These systems are typically used to power larger appliances such as air conditioners, heaters, and motors. Line voltage systems are typically more efficient than low voltage systems and require less wiring and less energy to transmit electricity. Line voltage systems are also more reliable and require less maintenance than low voltage systems. In addition, line voltage systems are more cost effective than low voltage systems as they require less equipment and materials.
