Should grounding conductors be allowed to daisy chain in this setup?

• A. Yes
• B. No
• C. Only for short runs
• D. Not specified

Answer: (B)

Grounding conductors must provide a continuous, low-impedance path back to the building’s grounding electrode system, with bonding arranged so all equipment shares a common ground reference. Daisy-chaining a grounding conductor between cabinets or pieces of equipment breaks that principle by introducing multiple small impedance segments and potential points of failure. If any splice or connection in the chain loosens or corrodes, equipment further down the line may lose its ground reference, and circulating stray currents (ground loops) can degrade RF performance or complicate fault clearing. The safe, reliable approach is to bond each piece of equipment to the main grounding system (via a bus or direct, well-bonded conductor) rather than chaining grounds from one device to another.
