When must an electrical worker ensure that a grounding electrode conductor is accessible?

The requirement for an electrical worker to ensure that a grounding electrode conductor is accessible during installation is grounded in safety and compliance with electrical codes. This accessibility allows for future inspections, maintenance, and potential modifications to the grounding system without the need for invasive work or requiring extensive access efforts.

Accessible grounding electrode conductors enable inspectors to verify that the system is installed correctly, properly sized, and adheres to the National Electrical Code (NEC) requirements. In the event of an electrical fault or malfunction, having easy access to the grounding system can facilitate quicker troubleshooting. Therefore, ensuring accessibility during installation supports ongoing safety and compliance, making it a crucial step in the process.
