The Bard 8407-012 buckboost transformer is an OEM electrical component used to correct incoming line voltage so Bard wall mounted HVAC equipment can operate at its intended 230V level when the site power is 208V, or to buck voltage when needed. This part is commonly applied in the unit electrical section to help protect motors and controls from improper supply voltage and to support stable starts and reliable operation. Use the unit wiring diagram and the Bard service literature to confirm the required boost or buck configuration, mounting location, and primary tap connections before installation, and replace with Bard 8407-012 to maintain proper fit and factory electrical performance.
