This test lead is used for detection during the inspection and maintenance of the power system. It is widely used in electrical maintenance, automatic electrical equipment, physics teaching, laboratories and other places for testing and debugging.SpecificationColor: BlueCurrent: 20AMaterial: Copper, PVCLead Length: 2m / 6.56ftPlug Size: 17 x 4mm / 0.67 x 0.16" (L*OD)Package List: 1 x Test LeadAdvantage1. The wire core is made of pure copper, designed with multiple strands of copper wire, and has good conductivity. Moreover, the core is wrapped by a PVC flame-retardant shell made of flexible insulating material, not easy to burn in case of fire.2. It is designed with a banana plug, made of pure copper nickel plated, not easy to rust and very durable. They are stackable. You can insert more than one plug into the same banana socket, which is very convenient to test different machines at the same time.InstructionConnect it into the circuit, check and repair the circuit, and test the machines.NOTEArrange the multi-wires in the circuit in order as much as possible, and do not twist the multi-wires together.Please pay attention to the length before you order.
