What type of connector is crimped onto a conductor for both splicing and termination purposes?

The correct answer is a solderless connector. This type of connector is specifically designed to be crimped onto electrical conductors, providing a reliable and robust connection for both splicing wires together and terminating them at a point such as a terminal block or a device.

Solderless connectors are a favored choice because their crimping process ensures a strong physical and electrical connection without the need for soldering, which can sometimes be less reliable if not done correctly. They are widely used in situations where quick assembly and disassembly are necessary, or where high temperatures or vibrations may compromise solder joints.

In contrast, while a split bolt connector and a bolt connector are used for joining conductors, they typically require a specific orientation and installation that may not be as straightforward as crimping a solderless connector. A mechanical lug is also used for connections but usually requires screws or bolts to secure the wire, making it less versatile for point-to-point connections compared to a solderless connector.
