NEC Commercial Electrical Practice Test

The connection of a grounding electrode conductor or bonding jumper to a grounding electrode must be what?

1. Loosely accessible

2. Completely accessible

3. Partially accessible

4. Not accessible

The correct answer is: Completely accessible

The connection of a grounding electrode conductor or bonding jumper to a grounding electrode must be completely accessible to ensure proper maintenance, inspection, and functionality. Accessibility is crucial because grounding systems are essential for electrical safety, helping to prevent hazardous situations such as electrical shock or fire. Having a connection that is completely accessible allows electricians and maintenance personnel to easily verify that the connection is intact, perform necessary tests, and make any repairs or adjustments as needed. This requirement is specified in the National Electrical Code (NEC) to promote safety and reliability in electrical installations. If connections were loosely or partially accessible, it could lead to oversight of necessary inspections or repairs, potentially resulting in unsafe electrical conditions. Conversely, connections that are not accessible at all would hinder any necessary evaluation or maintenance, which defeats the purpose of ensuring electrical safety. Thus, completely accessible connections are essential for compliance with safety standards and effective electrical system performance.
