Which type of wire should wire-wrap not be used with?

Wire-wrapping is a technique typically used with solid, single-core wire due to its ability to create reliable connections without soldering. It involves wrapping a finer gauge wire around the terminal, which can securely grip the wire and ensure a stable electrical connection. Stranded wire, on the other hand, consists of multiple smaller wire strands twisted together, which may not hold as securely during the wrapping process. The movement of the strands can lead to weaker connections when subjected to stress or vibration in a system.

This distinction is crucial in maintaining effective electrical connections in applications where reliability is essential, thus making stranded wire unsuitable for wire-wrapping. Single-core wire provides the necessary rigidity and surface contact area needed for a successful wrap, while insulated and high-voltage wires may have additional considerations for safety and insulation integrity, but are not inherently incompatible with the wire-wrapping process.
