What type of installation would likely NOT benefit from a punch down tool?

A punch down tool is primarily used for terminating wires into a patch panel or a punch down block, commonly seen in structured cabling systems. In the context of different types of installations, the utility of such a tool varies based on the specific wiring needs.

For single wire installations, the typical scenarios involve connecting one wire directly to a device or a single connection point without needing to integrate multiple wires into terminals or blocks. In contrast, setups such as Voice over IP, residential wiring with multiple lines, and cable installations often involve multiple wires that need to be organized, terminated, or connected to panels or blocks where a punch down tool would be invaluable. Therefore, a single wire installation does not require the use of a punch down tool, as it simplifies the connection process which does not necessitate the features that a punch down tool provides—primarily, the ability to efficiently connect multiple wires into a common termination point.
