2. During the soil type test, Type I soil will drain completely in less than two hours, while Type II soil will drain in more than two hours.

a. True

b. False


3. Is additional drainage recommended at project sites with Type I soil?

a. Yes.

b. No.

c. No, unless the site contains areas covered in concrete, planter areas and areas subject to heavy rainfall, in which in-grade fixtures may benefit from additional drainage support.

d. Soil type does not impact the amount of drainage necessary for an in-grade installation.


4. Which type of in-grade installation technique includes a sub-surface perforated pipe, commonly referred to as a French Drain?

a. Standard Type I installation

b. Standard Type II installation

c. Advanced Type II installation

d. Premium Type II installation


5. Which type of recessed in-grade fixture is designed to allow water to pass through the fixture and drain into the soil below, without damaging the optical compartment inside the fixture?

a. Direct burial light

b. Well light

c. Pole light

d. Recessed troffer


6. Which IP rating is the highest possible rating and indicates that the fixture can withstand exposure to dust, dirt, and particles and complete submersion in water over 1 meter in depth for one day?

a. 68

b. 67

c. 66

d. 00


7. What is the function of a transformer in terms of bringing power to a fixture?

a. A transformer brings line voltage from the power company into a residential or commercial building.

b. A transformer turns low-voltage power into line voltage.

c. A transformer is not involved in bringing power to an in-grade fixture.

d. A transformer steps down the line voltage power from its original 120V-277V to the lower voltage of either 12V or 24V.


8. Which of the following accurately describes the difference between an integral transformer and a remote transformer?

a. An integral transformer is included as part of the fixture. A remote transformer is entirely separate from the fixture.

b. A remote transformer is included as part of the fixture. An integral transformer is a separate, stand-alone transformer.

c. A remote transformer controls an integral transformer.

d. There is no difference between an integral and remote transformer.


9. Why is it important to determine whether a low-voltage in-grade fixture will have an integral transformer or a remote transformer?

a. The type of transformer affects how the power needs to be run to every recessed in-grade fixture in the system.

b. This decision can affect costs of installation and the serviceability of the system.

c. A noticeable voltage drop can occur when running low-voltage wire from a remote transformer to the low-voltage fixtures in a system, affecting light output.

d. All of the above


10. When specifying an LED in-grade fixture, what benefits can a magnetic transformer offer when compared to an electronic transformer?

a. A magnetic transformer is typically more durable and reliable than an electronic transformer.

b. A magnetic transformer is capable of igniting at 1W, a much lower minimum than some electronic transformers, and has greater distance capabilities.

c. A magnetic transformer is more energy efficient than an electronic transformer.

d. A and B

e. B and C
