Megger 6220-822 2-Piece Control Circuit Lead Clip Set, 1kV, 10' Length

The Megger 6220-822 two-piece control circuit lead set with compact insulated test clips includes one red and one black test lead for use with Megger 5- and 10-kilovolt (kV) insulation resistance testers when testing low-voltage circuits. Each 10' (3 m) test lead has a standard probe tip that is held against the conductor during testing. The set includes two insulated compact test clips that fit onto the test probes for hands-free connection to a conductor where there is limited access. Silicone insulation on the lead wires helps protect hands from shock and heat, resists melting or becoming brittle in hot or cold environments, and maintains flexibility better than PVC insulation. The test leads lock into the input jacks on the meter to help ensure a secure connection and reduce risk of shock. The compact test clips measure 1" x 2.2" (25 x 58 mm, W x D, where W is width, the horizontal distance from left to right; D is depth, the horizontal distance from front to back) and have a 0.7" (18 mm) jaw opening. The insulated clips and leads are rated for a maximum input of 1 kV of direct current (DC) voltage.

A test probe, test lead, test prod, or scope probe transmits an electrical signal to a testing device for display and analysis. Designs range from simple test leads with probe-style or clamp-on tips to more complex oscilloscope probes and current detectors. Some test probes, such as basic test leads, have wires with tips for connecting to test equipment. Other test probes, such as voltage detectors, are built into the meter. Depending on what is to be tested, the probe might either be passive or have active parts that require external power to operate. Some probes require contact for testing, while some are capable of taking measurements from a distance. Some also have finger barriers, insulation, or other features to help protect the operator's hand from electrical shock and burns. Test probes are rated according to the amount of voltage, current, temperature, or other input they can measure. When choosing a test probe, the maximum amount of input that the probe can measure should match or exceed both the maximum amount that can be tested by the test equipment, as well as that of the property expected to be present in the application.
