What is the appropriate bending radius of a bonding block?

The appropriate bending radius of a bonding block is five times the diameter of the cable. This specification is crucial because it ensures that the cable is not under excessive stress, which could lead to damage or impair its performance. Cables, especially those that carry electrical signals or data, have a minimum bending radius designed to maintain their integrity and functionality.

By adhering to this guideline, technicians are able to minimize the risk of signal degradation or physical damage to the cable's insulation and shielding. This is especially important in environments where cables are subjected to movement or shifts in location, ensuring that the connections remain stable and reliable.

The other choices suggest larger or smaller bending radii that do not align with industry standards and could lead to potential issues with cable management and performance. For instance, a smaller radius could create excessive strain on the cable, while a larger radius could be unnecessary and potentially complicate installations.
