Question

To verify an electrically safe work condition, all these conditions should be confirmed EXCEPT?

1) The presence or absence of voltage
2) Sources of electrical supply are determined
3) Phase conductors are grounded
4) Disconnecting devices are closed

Answer 1

To verify an electrically safe work condition, all conditions should be confirmed except grounding the phase conductors.

Step-by-step explanation:

To verify an electrically safe work condition, it is important to confirm the following conditions:

1) The presence or absence of voltage
2) Sources of electrical supply are determined
3) Phase conductors are grounded
4) Disconnecting devices are closed

The exception mentioned in the question is that the phase conductors should NOT be grounded to verify an electrically safe work condition.

For electrical safety, it is crucial to ensure that voltage is absent, sources of electrical supply are identified, and disconnecting devices are closed. This helps in preventing thermal and shock hazards.
