Frequently asked questions
What tool do I need to use this wire?
A wire-wrap tool, either manual or powered, is used to wrap the wire tightly around square wire-wrap posts. Use it on sockets and boards designed for wire-wrap connections.
Is this wire suitable for high-current or mains wiring?
No. A 0.25mm conductor is intended for low-current signal and prototyping connections. For higher currents or mains voltages, use wire with an appropriate cross-section and insulation rating.
