Question 1: During the installation of a main service panel, how do you ensure proper neutral-to-ground separation for safety?

Which action should you take?

Choose only one option

By connecting the neutral wire directly to the panel's ground bar

By grounding all circuit conductors through the neutral bus

By using a neutral bus bar that is isolated from the panel's metal enclosure

By reducing the number of ground rods used in the installation

Question 2: How does reactive power in an AC circuit affect circuit design for lighting and motor loads?

Which action should you take?

Choose only one option

It reduces the total power demand, lowering conductor size requirements

It increases the total power consumption without affecting the design

It causes the current to lag the voltage, requiring adjustments to conductor sizes

It has no impact on the circuit design for lighting

Question 3: When designing subpanels in a residential setting, what is the required neutral-to-ground separation?

Which action should you take?

Choose only one option

The neutral should be bonded to the ground at every point

The neutral and ground should be bonded together

The neutral and ground should be isolated in subpanels

Neutral and ground should only be separated in a main panel

Question 4: When troubleshooting an outlet that isn't working, how do you check if the problem is with the wiring or the outlet itself?

Which action should you take?

Choose only one option

By replacing the outlet with a new one

By testing the outlet terminals for voltage using a voltage tester

By bypassing the outlet and testing continuity of the wire

By inspecting the condition of the outlet's faceplate

Question 5: In electric motor wiring, how does the start capacitor contribute to the motor's operation during the initial power-up phase?

Which action should you take?

Choose only one option

It reduces the amount of current required for normal operation

It isolates the motor from power surges

It provides an initial boost of power to help the motor start turning

It limits the voltage to prevent overloading the motor

Question 6: What is the most common cause of an electrical shock when troubleshooting live circuits?

Which action should you take?

Choose only one option

Failing to ground test equipment

Contacting a live wire or terminal without proper insulation

Using the wrong type of test equipment

Inadequate circuit protection
