Final answer:
Before installing grounds on a conductor, it must first be verified as de-energized. Grounding ensures that the conductor is safely fixed at zero volts by connecting it to the earth, which is an essential safety practice to prevent electric shocks.
Step-by-step explanation:
Before installing grounds on a conductor, it should first be verified as de-energized. Grounding is the process by which a conductor can be fixed at zero volts by connecting it to the earth with a good conductor. This ensures that any potential voltage is safely discharged into the earth, preventing unintended shocks or electrical discharges. Grounding serves as a crucial safety measure, particularly for the metal cases of electrical appliances, to ensure they are at zero volts relative to the earth and reduce the risk of electric shock.
