Transformer disconnects mount inside or outside a control system enclosure and provide power to auxiliary single-phase loads when the main three-phase disconnect is either "on" or "off." The transformer disconnect is normally wired to the line side of the control panel's main disconnect. This convenient source of 120 V power can be used for auxiliary or isolated loads, such as panel lighting, portable power tools, and programmable controller equipment.
