What should personnel ground straps maintain for effective grounding?

The goal of personnel ground straps is to ensure effective grounding, which is essential for safety and the proper functioning of equipment. The optimal condition for grounding in many applications is to maintain low resistance to effectively discharge static electricity and prevent electrical shocks.

While the option suggesting a minimum resistance of 250,000 ohms might seem plausible, it is important to note that high resistance can limit the effectiveness of grounding. Ground straps are generally most effective when they allow for minimal resistance, thus enabling them to provide a reliable path for electrical discharge.

A resistance above a certain threshold could indicate a poor ground connection, potentially leading to static buildup and increasing the risk of electrical hazards. Typically, for effective grounding practices, a standard of less than 1,000 ohms is preferred to ensure adequate grounding capability, which is reflected in other options.

In practices focused on safety and efficiency, maintaining a low resistance ensures that personnel are adequately protected and that any electrical faults can be effectively managed.
