Question

Begin working on electrical equipments only when they are energized. (True/False)

Hint:

Always treat every electrical circuit as live and dangerous until you have personally verified it is de-energized using a reliable, calibrated voltage tester.

Answer 1

Step 1: Reviewing Electrical Safety Standards:
Working on live, energized electrical equipment is one of the most dangerous practices in any industrial or residential setting. It exposes the technician to severe risks of electric shock, electrocution, and arc flash burns.

Step 2: Safe Working Procedures:
Standard safety protocols (such as Lockout/Tagout or LOTO) require that before anyone touches or services electrical equipment, they must:

• De-energize the equipment by isolating it from the power source.
• Lock out and tag the isolation switch so it cannot be turned back on accidentally.
• Test the circuit using a verified voltage tester to confirm it is dead.
• discharge any residual capacitive energy using a grounding or shorting probe.

Step 3: Conclusion:
Because you should only work on electrical equipment when it is de-energized, the statement is False.
