Question 1: How do you handle wiring that has been damaged by an electrical surge from nearby lightning strikes?

Which action should you take?

Choose only one option

Inspect and replace any wire insulation that has been compromised by the surge

Replace the damaged sections of wire and check for any affected appliances or circuit breakers

Use a surge protector in the system to mitigate future surge risks

Use a megohmmeter to ensure no current leakage from the damaged areas

Question 3: What is the correct procedure to follow when repairing a circuit with multiple wire splices in a junction box?

Which action should you take?

Choose only one option

Use a twist-on wire connector and secure the splices with electrical tape

Use a terminal block to organize and connect all wires in a secure manner

Solder all the wire connections and cover with heat shrink tubing for added protection

Ensure each splice is properly twisted and covered with wire nuts or crimp connectors

Question 4: What instrument is most suitable for detecting voltage imbalance in a three-phase system?

Question 5: In circuit repair, what does it mean if a breaker trips due to overload?

Which action should you take?

Choose only one option

The load exceeds the circuit's design capacity

The breaker is faulty and needs replacement

The wire insulation is damaged

The wire gauge is too small

Question 6: When performing electrical maintenance on a circuit breaker, what is the correct procedure to check for contact wear?

Which action should you take?

Choose only one option

Use an infrared thermometer to check for hot spots

Inspect visually for corrosion

Measure the contact resistance with a micro-ohmmeter

Check the breaker's tripping mechanism for smooth operation
