• A. FALSE
• B. Not Applicable
• C. TRUE
• D. Unknown

Answer: (C)

The emergency electrical cutoff switch is designed to stop electrical power to key components so the system moves to a safe, default state during an emergency. Placing it to CUTOFF removes power to the 2000 psi isolation valve, which is an electrically controlled valve in the high-pressure hydraulic circuit. Without power, the solenoid de-energizes and the valve shifts to its default, isolated position. This prevents hydraulic flow through that part of the system and helps contain pressure and potential leaks until normal power is restored. In short, the switch directly disrupts the valve’s electrical actuation, causing the isolation valve to default to the safe, isolated state.
