In New York City, Type SE (Service Entrance) cable is specifically designed for service applications and is suitable for installations rated not over 600 volts. This type of cable is constructed to withstand the rigors of service entrance installations, including both exposed and concealed applications.

Type SE cable is also notable for its robust construction which includes conducting conductors covered by an outer jacket that protects against environmental factors, making it ideal for connecting the service drop to the building’s electrical system.

Other cable types listed, like Type NM (non-metallic sheathed cable), Type UF (underground feeder cable), and Type AC (armored cable), have different applications and characteristics. For instance, Type NM cable is commonly used for interior wiring in residential buildings, while Type UF is designed for outdoor use in wet locations. Type AC is primarily utilized where physical damage is not a concern and where flexibility is needed. However, none of these cables are specifically intended for service entrance applications, which is why Type SE is the correct choice for services not rated over 600 volts in this context.
