For community antenna systems, what can the bonding conductor be connected to?

The bonding conductor for community antenna systems can be connected to power service accessible means external to enclosures. This option is essential because it ensures that the bonding conductor provides a reliable path to ground, which is crucial for safety and the protection of equipment from electrical faults. By connecting to power service points that are accessible and external, it allows for proper grounding practices that comply with safety standards, reducing the risk of damage or hazards due to lightning strikes or surges.

The other options entail connections that either do not meet safety codes or could potentially create a hazardous situation. For instance, connecting to any ungrounded point in the structure does not provide the necessary safety and may lead to unwanted electrical potentials that could endanger users or equipment. Similarly, limiting connections only to the main service panel may not always be feasible or safe, depending on the layout of the installation. Lastly, stating that no connections are allowed would contradict the fundamental need for grounding in electrical installations, which is essential for the proper function and safety of community antenna systems. Thus, connecting the bonding conductor to power service accessible means external to enclosures is the most appropriate and safe choice.
