Why should an electrical worker determine the nominal voltage of a circuit first before making contact with the circuit? |
A) So the worker can select the proper voltage tester to use before contact with the circuit is made. |
B) So the worker can select the proper PPE and voltage tester to use before contact with the circuit is made. |
C) So the worker can select the proper PPE to use before contact with the circuit is made. |
D) As long as the circuit is properly tagged/locked out, no determination of the nominal voltage is necessary. |
