Question 4: What method should an Electrician use to test an electrical system after installation?

Which action should you take?

Choose only one option

Use specialized testing equipment to check for continuity, voltage, resistance, grounding, and correct functionality of the entire system

Perform basic continuity tests without checking load

Use only visual inspections to test the system

Skip testing and assume everything is functioning

Question 5: What is the purpose of overcurrent protection devices such as breakers in electrical systems wiring?

Which action should you take?

Choose only one option

They enhance the system's performance by maintaining constant current

They limit voltage fluctuations within the system

They prevent excessive current from damaging the wiring or causing fire hazards

They focus solely on preventing short circuits

Question 6: How do you detect a short circuit in a wiring system?

Which action should you take?

Choose only one option

By visually inspecting the wire for physical damage

By replacing all components in the circuit

By testing the continuity of the circuit with a multimeter

By checking the fuse or circuit breaker for signs of damage
