Sample 1 — Administration General Regulations
Question: A master mechanical contractor is designing the heating system for interior office spaces intended for human occupancy. The space-heating system must be capable of maintaining what indoor temperature, and at what measuring height, on the design heating day?
- A. 65°F at 3 feet above the floor
- B. 68°F at 3 feet above the floor
- C. 68°F at 5 feet above the floor
- D. 70°F at 3 feet above the floor
Correct Answer: B
Per IMC 309.1, interior spaces intended for human occupancy shall be provided with active or passive space-heating systems capable of maintaining an indoor temperature of not less than 68°F (20°C) at a point 3 feet above the floor on the design heating day. Portable space heaters cannot be used to comply.
Reference: IMC 2018 Section 309.1
Sample 2 — Appliances & Mechanical Equipment
Question: A duct furnace is installed in a system where the supply ducts convey air to areas outside the space containing the furnace. Relative to the circulating air blower, where must the duct furnace be installed?
- A. Upstream of the blower in the return plenum
- B. On the positive pressure side of the blower
- C. On the negative pressure side of the blower
- D. In the return duct ahead of the filter rack
Correct Answer: B
IFGC 610.4 requires the duct furnace to be installed on the positive pressure side of the circulating air blower, and requires return air to be conveyed by duct(s) sealed to the furnace casing and terminating outside the space containing the furnace.
Reference: IFGC 2018 Section 610.4
Sample 3 — Duct Systems
Question: Electrical equipment having a combustible enclosure is exposed within a ceiling return air plenum. The equipment shall be listed and labeled for such use in accordance with which standard?
- A. UL 723
- B. UL 1887
- C. UL 2043
- D. UL 181A
Correct Answer: C
IMC 2018 Section 602.2.1.4.2 requires electrical equipment with combustible enclosures exposed within a plenum to be listed and labeled for such use in accordance with UL 2043. UL 723 is a surface burning characteristics test, UL 181A covers closure systems for fibrous glass duct, and UL 1887 applies to plastic fire sprinkler piping in plenums.
Reference: IMC 2018 Chapter 6 — Section 602.2.1.4.2 Equipment in combustible enclosures
Treat your first attempt as a checkup, not a verdict. After every attempt, the results page breaks your score down by outline topic, so you can see which topics need work. Compare your score with the real exam's passing score, a minimum score of 75, and keep practicing until you pass consistently.
