Which of the following describes a service drop?

A service drop is defined as the overhead conductors that deliver electric power from the utility's distribution system down to a customer's service point, typically the point at which electricity enters a building. This connection plays a critical role as it ensures that electricity is supplied safely and reliably from the utility provider to the individual consumer’s premises.

Overhead conductors are commonly utilized in areas where it is practical to run power lines above ground. They are often supported by poles or other structures and directly connect the distribution system to the customer’s service entrance. This connection is fundamental in residential and commercial settings where utility services are provided.

The other options refer to different types of wiring configurations or systems. For instance, underground wires are utilized in different scenarios and are not considered service drops. Wires connecting two buildings are categorized separately as building-to-building connections rather than a direct utility service drop. Lastly, conductors used for temporary power, such as during construction or special events, have a distinct classification and purpose that differs from the standard service drop configuration. Understanding these distinctions is essential for anyone involved in load calculations and utility service installations.
