• 10 inches

• 50 inches

• 100 inches

What is the primary function of a 3-way switch?

• To control a light fixture with a timer.

• To control a light fixture with a remote control.

• To control a light fixture from two different locations.

• To control a light fixture with multiple levels of brightness.

How does a 3-way switch system work?

• It uses two switches that are wired in series to control the light fixture.

• It uses a single switch with multiple contacts to control the light fixture.

• It uses two switches that are wired in parallel to control the light fixture.

• It uses two switches that are wired in a combination of series and parallel to control the light fixture.

You are installing a 3-way switch system for a hallway light. What type of wire would you use to connect the two switches?

• THHN wire

• Ground wire

• Coaxial cable

• Romex (NM-B) cable

Why is it important to use traveler wires when wiring a 3-way switch system?

• To prevent electrical shocks.

• To control the brightness of the light fixture.

• To ensure the light fixture is properly grounded.

• To provide a path for the electrical current to flow between the two switches.

You are installing a 3-way switch system for a staircase light. How would you determine the best location for the two switches?

• Place the switches at the entrance and exit of the room.

• Place the switches at the top and bottom of the staircase.

• Place the switches at the beginning and end of the hallway.

• Place the switches in a location that is convenient for the user.

You are comparing a 3-way switch system to a dimmer switch for controlling a living room light. Which option would be a better choice and why?

• Dimmer switch, because it is easier to install.

• 3-way switch system, because it is less expensive.

• 3-way switch system, because it provides more control over the light fixture.

• Dimmer switch, because it allows you to adjust the brightness of the light fixture.

What is the difference between a 3-way switch and a 4-way switch?

• A 3-way switch is less expensive than a 4-way switch.

• A 3-way switch uses two traveler wires, while a 4-way switch uses three traveler wires.

Why is it important to use the correct type of wiring when installing a 3-way switch system?

• To prevent electrical shocks.

• To ensure the switches operate correctly.

• To ensure the light fixture is properly grounded.

• All of the above.

You are troubleshooting a 3-way switch system that is not working properly. How would you use a multimeter to identify the problem?

• Measure the resistance of the wires.

• Check the continuity of the circuit.

• Measure the voltage across the switches.

• All of the above.
