True or False: The underground riser provides fused protection and an isolating device for the underground cable.

The statement is true because the underground riser is designed to provide both physical protection and isolation for underground cables. By serving as a conduit, the riser helps to safeguard the cable from environmental factors, such as moisture and mechanical stress, which could lead to damage or failure. Additionally, it creates an isolation point that can be essential for maintenance and safety, as it allows for disconnection and work to be performed without affecting the overall system. This combination of protection and isolation is crucial for ensuring the integrity and reliability of underground electrical installations.
