Answer

All statements are true according to NEC requirements. Explanation 1. Identify the key requirement for grounding electrode systems The National Electrical Code (NEC) requires that all grounding electrodes present at a building must be bonded together to form a grounding electrode system. 2. Analyze each statement - "All grounding electrodes that are available at the building must be bonded together." This aligns with NEC requirements. - "All grounding electrodes that are present at the building must be bonded together." This also aligns with NEC requirements. - "If present, the following electrodes must be bonded together: underground metal water pipe and a ground ring." This is true as per NEC. - "If present, the following electrodes must be bonded together: metal structural member electrode and a ground rod." This is true as per NEC. 3. Determine the incorrect statement None of the statements provided contradict the NEC requirements for bonding grounding electrodes.
