Question 1: When troubleshooting an electric stove that is not heating properly, what is the first step in determining the cause?

Which action should you take?

Choose only one option

Check the stove's temperature sensor

Inspect the wiring for physical damage

Check if the element has continuity

Measure the current being drawn by the stove

Question 2: In designing a 3-phase circuit for a commercial building, what is the most important factor to consider?

Which action should you take?

Choose only one option

The voltage and load balance between the phases

The color coding of the wires

The number of outlets needed

The size of the conduit used

Question 3: What is the correct method for grounding electrical systems in a commercial building?

Which action should you take?

Choose only one option

Use a dedicated ground conductor, connect all metallic parts to the ground, and follow local electrical codes for grounding electrodes

Disregard grounding if the system is insulated

Use the neutral conductor for grounding

Use any available metal surface for grounding

Question 4: When installing a lighting circuit, which of the following is true about switch legs in electrical installations?

Which action should you take?

Choose only one option

The switch leg only connects to the ground wire

The switch leg should be a continuous wire between the switch and the light, carrying the load

The switch leg is connected directly to the neutral wire

The switch leg is connected to the breaker in the panel

Question 5: If you discover that a circuit breaker is buzzing but not tripping, what is the most likely cause of the problem?

Which action should you take?

Choose only one option

An overloaded circuit that has not tripped

A defective neutral connection

A weak or faulty breaker

A short-circuit condition between wires

Question 6: In three-phase circuit design, how do you calculate the total power delivered to a load?

Which action should you take?

Choose only one option

By summing the power of all individual phases

By using the formula P = ?3 x V x I x Power Factor

By multiplying the voltage by the current in a single-phase system

By using the formula P = V x I
