Test Lead Wire

Test Lead Wire refers to flexible electrical lead wire used to create temporary connections between test instruments and a device or circuit under evaluation. It is designed to provide a reliable conductive path for measurement and troubleshooting tasks while allowing frequent handling and repositioning.

Within the Wire & Cable category, test lead wire is commonly supplied as individual leads or as part of general test lead assemblies, and is selected for stable electrical continuity and mechanical flexibility during repeated use.

• Purpose: Enables temporary electrical connections for testing and measurement.
• General construction: Conductive core with an insulating outer layer for handling and basic protection.
• Category scope: Covers lead wire intended for test and diagnostic interconnections.
