Under NBFAA minimum standards, if a device provides a grounding terminal, what is required?

• A. Grounding is optional if the system is low voltage.
• B. Grounding is required only for metallic enclosures.
• C. Grounding is not required if a grounding terminal is provided by the manufacturer.
• D. Grounding shall be performed under NEC, UL, or manufacturer standards; when the manufacturer provides a grounding terminal, grounding shall be required.

Answer: (D)

Providing a grounding terminal means the device is designed to be bonded to the building’s protective earth. Under NBFAA minimum standards, grounding must be performed according to the applicable requirements, typically the NEC and UL listings or the manufacturer's instructions. You connect the grounding conductor to the device using the terminal the manufacturer provides, ensuring the connection meets those recognized standards. This keeps the equipment safely bonded, reduces shock risk, and helps prevent stray currents from affecting system operation. Grounding is not optional, it applies to more than just metallic enclosures, and the presence of a grounding terminal does not waive the requirement to bond the device.
