Which type of cable is classified as Type SE?

Type SE cable is defined in the National Electrical Code (NEC) as Service Entrance Cable. It is specifically designed to be used for electrical service entrance applications, where power is brought into a building. This type of cable is typically constructed with conductors that are insulated and bundled together, and it often has a durable outer jacket that provides protection against environmental factors.

Type SE cable is particularly important for safe and effective electrical service because it is engineered to handle higher voltage and provides enhanced insulation. This cable can be run overhead or underground, and it is used for both residential and commercial applications. The specific construction and labeling of Type SE ensure that it meets the required safety standards for service entrance applications.

Unlike the other types of cables mentioned, such as Metal Clad Cable, Flexible Metal Conduit, and Nonmetallic-Sheathed Cable, Type SE has a unique designation and application that aligns with its intended use in bringing electricity into a structure, confirming it as the proper classification for this cable type.
