What is the stated reason to run a reversed ground circuit?

• A. To reduce cost
• B. To improve safety
• C. So the ground can never be phased
• D. To simplify wiring

Answer: (C)

Ground is the safety reference that stays at essentially zero volts and provides a path for fault current. The idea behind wiring a circuit with the ground arranged in a “reversed” way is to keep that protective conductor tied to earth so it cannot take on a phase relationship with the live conductors. In other words, the ground path remains non-energized relative to the supply and cannot become a live, phased conductor, which helps prevent shock hazards on equipment frames or enclosures. This is why the stated reason is to ensure the ground can never be phased. It’s not about cost or simplifying wiring; it’s about preserving the ground as a safe, non-energized path.
