After checking all protective devices, what should be confirmed next in the startup sequence?

• A. Switches or breakers for accessories are in the OFF positions
• B. Fuel pump circuit breaker
• C. Engine run (gen field) and control (control) switched on
• D. Isolation switch OFF

Answer: (A)

The next step is to confirm that the switches or breakers for accessories are in the OFF position. This keeps all nonessential loads from drawing power or creating unexpected energizing during the startup checks. By ensuring accessories remain off, you prevent accidental operation, arcing, or backfeeding into the system while you verify protection devices and set up the core startup sequence. Once this is confirmed, you would typically progress to energizing the required systems in a controlled order (such as turning on needed fuel or control circuits later, not before making sure accessories are isolated). The other options involve energizing or leaving the system in a state that could enable loads or disrupt the start, so they aren’t the appropriate next step.
