For three-wire products with black, white and green wires, jumper J3 is required. In this case, the Ground Check switch on the back panel of the hipot tester is turned ON. The black and white wire are connected to the RED alligator clip on Jumper J3, the green wire is connected to the BLACK alligator clip on Jumper J3. The other supplied lead is a black banana plug/alligator clip jumper that is connected between the RETURN receptacle on the hipot tester and exposed dead metal on the product being tested. Most all permanently connected products will use J3. J3 can also be used to test two wire products by leaving the BLACK alligator lead on Jumper J3 disconnected, and turning the Ground Check switch on the back panel of the hipot tester to the OFF position.

Order Option J3 for three wire products.

See Option J2 for two wire products.
