What is the component in a hand hole (pull box) used for connecting services?

The correct answer is the component called a mole, which serves an essential role in hand holes or pull boxes for connecting services. The mole is a device that allows for the splicing and joining of different service cables, facilitating the communication of electrical current or data between them. It is specifically designed to accommodate multiple conductors in a compact space, thereby providing a reliable and accessible connection point for maintenance or upgrades.

In contrast, a junction box is primarily used for housing connections rather than directly providing a service connection. Terminal blocks serve specific functions, generally related to the organization and distribution of electrical signals but do not perform the same splice function as a mole. A service bar, while it may carry electrical services, is typically not the specific component referenced in the context of a pull box used to connect services. Each component has its own role, and understanding these distinctions helps clarify the purpose of each in electrical installations.
