Which type of service-entrance cable has a flame-resistant and moisture-resistant covering?

Type SE (Service Entrance) cable is specifically designed for use in the service entrance of a building, providing a connection from the utility supply to the building's electrical system. One of its key characteristics is that it has a flame-resistant and moisture-resistant covering, making it suitable for outdoor and exposed applications. This quality helps protect the wiring from environmental damage and reduces the risk of fire hazards, which is crucial for safety and compliance with electrical codes.

In contrast, other cable types have different applications and protective features. For example, Type NM (Non-Metallic Sheathed Cable) is commonly used in residential wiring but does not have the same high resistance to moisture and flame as Type SE. Type UF (Underground Feeder) cable is designed for direct burial but may not have the same level of flame resistance as Type SE. Type AC (Armored Cable) is made for specific installations where physical protection is required, but it may not offer the same moisture resistance in all scenarios as Type SE does. This makes Type SE the preferred option for reliable service entrance installations.
