The Megger 1008022 3-Piece Insulated Test Lead Clip Set, 3kV Test Voltage is a set of 3 insulated test leads with clips. This set includes one red, one blue, and one black test lead for use with Megger 5 kV and 10 kV insulation resistance testers. Each 10 foot (3 m) test lead has a medium sized test clip for hands-free connection to a conductor. The silicone insulation on the lead wires and test clips helps protect hands from shock and heat, resists melting or becoming brittle in hot or cold environments, and maintains flexibility better than PVC insulation.
