If the EMER BUS FDR FAIL annunciator comes on, the emergency relay opens and the emergency bus receives power from which bus?

In the Beechjet 400A, the emergency bus is kept alive by a dedicated feed through the emergency relay, so it remains powered even when the normal power path trips or fails. When the EMER BUS FDR FAIL annunciator comes on, that emergency relay opens to isolate the main feed and tie the emergency bus to the left-hand load bus. This design designates the left load bus as the source for emergency power, ensuring critical systems stay powered.

Power from the right-hand load bus, the main power bus, or the battery charge bus isn’t used to supply the emergency bus in this scenario, which is why the left-hand load bus is the correct source.
