Which cables and conductors are allowed to be attached to a service mast?

The correct choice, which pertains to electric power, is due to the specific requirements and safety standards established for service masts. Service masts are vertical structures that support service drop conductors, primarily for electrical power distribution. These masts have to safely carry the electrical load and facilitate a secure connection to the utility’s power service.

Electric power cables are designed to handle higher voltages and currents that are typical in utility services, and they adhere to stringent regulations regarding insulation, load capacity, and physical durability. This ensures safety and compliance with electrical codes, as improper attachments could lead to hazards such as electrical fires or running the risk of electrocution.

In contrast, while data cables, telephone cables, and television cables may be used in various installations, they do not meet the requirements necessary for connections at the service mast level where electric power is concerned. Typically, these types of cables are installed in a separate manner that does not interfere with or compromise the safety of the power supply's integrity. Therefore, it's important to recognize the distinction in applications and regulations that govern which cables can be securely and safely attached to a service mast.
