What is the maximum allowable distance between protective grounds?

The maximum allowable distance between protective grounds, which is essential in ensuring safety during electrical work by providing an effective path for fault current, is indeed 2 miles. This limit is specified in various safety regulations to maintain effective grounding and ensure personnel are protected during maintenance or repair work on electrical systems. Beyond this distance, the risk of voltage surges increases, which can compromise worker safety and the effectiveness of the grounding system. Thus, adhering to the 2-mile guideline is crucial for maintaining safety standards and protecting both personnel and equipment in electrical work.
