Which is not a stated purpose of grounding and bonding for limited-energy systems and communications equipment?

• A. Provide shock protection
• B. Limit voltage surges
• C. Provide a return path for fault currents
• D. Improve signal integrity

Answer: (D)

Grounding and bonding for limited-energy systems and communications equipment are about safety and reliable fault handling. Establishing a solid earth reference keeps exposed metal parts at ground potential to protect people from shock. Bonding creates a low-impedance path so fault currents return quickly to the source, allowing protective devices to trip and limit damage. A proper ground also helps keep voltages from rising too high during faults or surges, reducing the risk of damage or shock. Improving signal integrity isn’t a formal, stated objective of grounding and bonding for these systems. While a good grounding scheme can influence noise and EMI indirectly, the primary aims are safety and fault control.
