Which type of cable is classified as Type SE?

Type SE, or Service Entrance Cable, is specifically designed for use in the service entrance of a building to connect the electrical service to the building's electrical system. It is constructed to withstand the exposure to the elements, such as moisture and sunlight, making it suitable for outdoor applications where the cable might be exposed. Type SE is often used to directly connect to power from the utility supply and can be installed in various configurations such as overhead, underground, or on the building's exterior.

This type of cable typically consists of conductors that are insulated and grouped within a single sheath, providing protection and simplifying installation. The NEC has specific requirements for the use of Type SE cable, ensuring safety and compliance with electrical standards for service entrances.

Understanding the characteristics and applications of Type SE is important for electrical professionals because it plays a crucial role in safely conveying electricity from the utility provider into residential and commercial buildings. Other options like Metal Clad Cable, Flexible Metal Conduit, and Nonmetallic-Sheathed Cable serve different roles and are subject to different code requirements.
