In order for a live-line tester to be used to test and prove dead a high voltage circuit, what must be done to verify the ability of the tester to detect a voltage?
A
The live-line tester need not be checked prior to testing the circuit to be worked upon as long as it has not been declared inoperative.
B
The live-line tester should be checked by connecting to a known high voltage source only before testing the circuit to be worked upon.
C
The live-line tester should be checked by connecting to a known high voltage source before and after the circuit to be worked upon is tested.
D
