Using the TVB-2 The TVB-2 load box consists of resistors of varying types that induce a PASS or FAIL condition depending on the test parameters that are set in your electrical safety tester. The 8 banana jacks located on the top of the box can be used to apply the corresponding load to the output of your tester.
