The bend radius of ground wire according to installation standards is commonly set at 2 inches. This is important because proper bend radius ensures that the wire does not become damaged during installation or over time, which could compromise its performance and safety. A larger bend radius allows the wire to maintain its integrity while minimizing stress and potential breakage.

Choosing 2 inches as the bend radius aligns with industry standards, ensuring reliable performance of the ground wire in electrical systems. A smaller bend radius could lead to kinks or physical damage, while a larger radius might not be practical for certain installations. Thus, adhering to the established standard of 2 inches helps ensure both the safety and functionality of the electrical system in which the ground wire is installed.
