Will selecting OVRD on the SHED BUSES knob connect the shed buses?

Will selecting OVRD on the SHED BUSES knob connect the shed buses?

• A. Yes
• B. Only if a generator is online
• C. No
• D. Only when battery voltage is above threshold

Answer: (C)

Shed buses are kept isolated to manage load on the electrical system, and the SHED BUSES control determines how those buses are treated by the system. The OVRD position overrides the automatic shedding logic, but it does not by itself physically connect the shed buses. The actual energizing of shed buses still depends on the bus ties closing and a usable power source being available. So selecting OVRD will not connect the shed buses.
