Textbook Problem

What can you do to reduce or eliminate the possibility of receiving an electric shock when working on electrical circuits? Circle the correct answer.

  1. Turn off the power on the circuit you are working on.
  2. Turn off the power on the circuit you are working on, tag it, and lock the disconnect in the OFF position.
  3. Turn off the power on the circuit you are working on, then tell everyone else working with you not to turn the power back on.

To determine

Choose the option that eliminates the possibility of receiving an electric shock by an electrician when he works on electrical circuits.

Explanation

Discussion:

Option a:

If an electrician just turns off the power and starts his work on an electrical circuit, there is a possibility that an unknown person can turn on the power and cause a sudden electric shock to the electrician. Therefore, option (a) is not advisable and it is an incorrect option.

Option b:

The possibility of receiving shock absolutely reduces if the electrician takes the precaution given in option (b). As the turn-off position is locked, it is not possible to turn on the power by someone else while the electrician is working on the electrical circuit...
