Which type of cable is used for the Service Entrance in the townhouse development?

The type of cable used for the Service Entrance in a townhouse development is Service Entrance (SE) cable. SE cable is designed specifically for the delivery of electricity from the utility power source to the main service panel. It is suitable for use both above and below ground, making it versatile for different installation scenarios, including residential properties like townhouses.

SE cable typically includes two or more conductors and an insulated ground, all within a durable outer jacket that provides protection from environmental elements. This construction is crucial for ensuring that the electrical system is both safe and efficient.

In contrast, UF (Underground Feeder) cable is typically used for underground wiring and does not have the same specifications for service entrance applications. USE (Underground Service Entrance) cable is used for below-ground service drops but may not be as suitable or necessary for above-ground entrances typical in townhouse developments. Service Oblique is not a standard term used in electrical installations, further differentiating it from the appropriate choice of SE cable.

The selection of SE cable ensures compliance with the National Electrical Code (NEC) and proper functionality for powering residential buildings.
