When you connect a grounded conductor to a terminal, the connection should not do what to the designated polarity?

• A. Reverse the designated polarity
• B. Change color
• C. Increase current
• D. Decrease voltage

Answer: (A)

Maintaining designated polarity is essential when wiring. The grounded conductor serves as a reference point and safety path, so connecting it to the terminal must not flip which side is considered positive or neutral. Reversing polarity can cause components that rely on a specific orientation—like diodes or polarized capacitors—to fail, create shock hazards, or energize parts of the equipment that should be at ground potential. The other effects listed (changing color, increasing current, or decreasing voltage) aren’t inherent outcomes of tying the grounded conductor to the terminal, whereas reversing polarity directly undermines correct operation and safety.
