Continuity Testing Quiz

What is the primary purpose of a continuity test?

• To check the power supply

• To identify the live wire

• To ensure electrical continuity in a circuit

• To measure voltage in a circuit

When should continuity testing be performed?

• Only during installation

• Before energizing a new electrical system

• Only during emergencies

• After a circuit has been damaged

What does a fuse do?

• Automatically resets after tripping

• Protects circuits from overcurrent by melting

• Detects leakage current to ground

• Operates based on heat generated by excess current

Which device interrupts the flow of electricity in case of overcurrent?

• Fuse

• Earth Leakage Relay

• Thermal Overload Relay

• Circuit Breaker

What is the function of an Earth Leakage Relay?

• To protect motors from overcurrent

• To detect leakage current to ground

• To measure voltage in a circuit

• To verify proper connections

What is the purpose of a live wire test?

• To measure current flow

• To check for continuity

• To reset circuit breakers

• To identify the live wire

Which tool is used to detect electric fields around live wires without contact?

• Voltage Detector Pen

• Multimeter

• Non-contact Voltage Tester

• Test Lamp

What should be done before conducting a live wire test?

• Wear personal protective equipment

• Ensure the circuit is de-energized

• Check the voltage with a multimeter

• Use a non-contact tester only

What indicates that a live wire has been detected?

• The tool vibrates continuously

• The tool displays a voltage reading

• The tool emits light or sound

• The tool shows no signal

What is a key feature of a circuit breaker?

• Automatically interrupts electricity flow

• Operates based on heat

• Single-use device

• Detects leakage current
