Is it required for an encased or buried connection to a grounding electrode to be accessible?

• A. Yes, it must always be accessible
• B. No, it does not have to be accessible
• C. Only if it is above ground
• D. Only if it is encased in concrete

Answer: (B)

The requirement regarding whether an encased or buried connection to a grounding electrode must be accessible is determined by the regulations set forth in the National Electrical Code (NEC). According to these regulations, it is not a necessity for these types of connections to be accessible. This means that if a grounding electrode is buried or encased in a non-removable covering, such as concrete or other materials, there is no requirement for the connection to be easily reachable for inspection or maintenance. The rationale here is that grounding electrodes serve a specific function in providing a path to dissipate electrical faults safely, and their operation does not depend on their accessibility. In contrast, other types of connections or equipment may require accessibility for routine maintenance or inspection, but that principle does not extend to buried or encased grounding electrodes.
