Final answer:
The statement is false; code regulations require that all present concrete-encased electrodes be bonded together to form one grounding electrode system for safety and performance.
Step-by-step explanation:
In a building or structure where there are multiple concrete-encased electrodes, it is generally permitted to bond only one of them into the grounding electrode system. Therefore, the statement is true.
The statement is false; code regulations require that all present concrete-encased electrodes be bonded together to form one grounding electrode system for safety and performance.
The statement that where more than one concrete-encased electrode is present at a building or structure, it shall be permitted to bond to only one into the grounding electrode system is false. According to the National Electrical Code (NEC), when multiple concrete-encased electrodes (also known as Ufer grounds) are present, they are required to be bonded together to form a single grounding electrode system. This ensures that there is a low-resistance path to earth, which is crucial for the safety and performance of the electrical system.
