What type of wiring is typically used for residential overhead service connections?

For residential overhead service connections, the wiring type commonly used is Type SE (Service Entrance) cable. This type of cable is specifically designed for the service entrance to a residential building, allowing it to handle the higher voltage involved in the incoming utility service.

Type SE cable is appropriate for outdoor use, as it is constructed to withstand the elements and has a durable design that can endure exposure to sun, moisture, and temperature fluctuations. It may also come with a sheath that provides additional protection against physical damage, which is important for overhead connections.

In contrast, other types of wiring like Type NM (non-metallic sheathed cable) and Type UF (underground feeder) are typically used for indoor wiring or underground installations respectively, and not suitable for overhead applications due to their limitations in weather resistance and voltage ratings. Type MC (metal-clad) cable, while suitable for some applications, does not meet the specific requirements and construction that Type SE provides for overhead service connections. Thus, Type SE is the preferred and correct choice for this application.
