RCDD Question #113: Real Exam Question with Answer & Explanation
The correct answer is C. Lightning protection system. This question tests knowledge of the mandatory bonding and grounding systems required at every telecommunications site, identifying which system is supplementary rather than universally required.
Question
Certain systems must exist relative to bonding and grounding at every site. Which of the following is NOT one such system?
Options
- AAC grounding electrode system (e.g., in some countries it may also be known as the earthing system)
- BTelecommunications bonding infrastructure
- CLightning protection system
- DEquipment grounding system (e.g., in some countries it may also be known as the equipment bonding
Explanation
This question tests knowledge of the mandatory bonding and grounding systems required at every telecommunications site, identifying which system is supplementary rather than universally required.
Common mistakes.
- A. The AC grounding electrode system (earthing system) is a required foundational system at every site, establishing the earth reference to which all other grounding systems connect.
- B. Telecommunications bonding infrastructure is a mandatory system that interconnects all metallic telecommunications components to a common ground reference, and is required at every site.
- D. The equipment grounding system (equipment bonding conductor) is a universally required system that protects personnel and equipment from fault currents at every installation.
Concept tested. Required vs. supplementary grounding and bonding systems
