What should be used to protect drop cable when routing through an exterior entry hole?

Using a feed through bushing to protect drop cable when routing through an exterior entry hole is appropriate because it serves as a barrier that reduces the risk of damage to the cable as it passes through the hole. The bushing provides a smooth edge, which prevents abrasion and wear on the cable, ensuring that it maintains its integrity and performance. This is essential for both the longevity of the cable and the quality of the signal it transmits.

Additionally, a feed through bushing, typically made from durable materials, can also help to seal the entry point against environmental factors such as moisture, pests, and debris. This added protection is vital for maintaining the reliability of the cable and the overall system performance.

In contrast, while other options may serve different purposes, they do not provide the same level of cable protection at entry points. For example, a fire-resistant cover is important for preventing fires but does not protect the cable from physical damage. Using a standard hole saw is a method for creating the entry hole but does not contribute to protecting the cable once the hole has been made. A PVC pipe could potentially house and protect a cable, but it is not specifically designed for transitioning cables through walls or other barriers as a feed through bushing is. Thus, the
