If an underground riser is low voltage, how does it terminate?

When dealing with the termination of a low voltage underground riser, it typically utilizes a weatherhead. A weatherhead is a type of fitting that helps keep water out of the conduit while also allowing for some flexibility in the connection. This is particularly important for risers, which run vertically and may be exposed to the elements at their termination point.

The weatherhead’s design prevents moisture from entering the conduit, which is crucial for maintaining the integrity and functionality of the electrical systems. Additionally, it provides a smooth transition between the underground wiring and the above-ground connections.

In contrast, other choices such as a transformer, junction box, or disconnect switch serve different purposes. A transformer is used for voltage conversion, a junction box is primarily designed to house and manage electrical connections, and a disconnect switch is for safely breaking the circuit. These components are essential in an electrical system but do not directly relate to the specific termination of a low voltage underground riser.
