# Electrical System The electrical system of the MH60 is designed to provide reliable power to all essential aircraft systems, including avionics, flight controls, sensors, and mission equipment. It consists of two **main AC generators**, each driven by one of the aircraft’s engines, and a third **APU generator** that provides power during ground operations or engine start. Each generator feeds into a **primary power bus**, which supplies power to critical systems. These buses are connected through power distribution relays and circuit breakers to the avionics and systems. Circuit breakers are not modeled in MSFS. A **battery** provides power to essential flight instruments during startup, and in case of generator failure. A ground power unit can be connected for startup as well. The electrical system is managed from the Electrical Panel, located on the overhead panel.
