1Which Hawaii state agency oversees the licensing of low voltage contractors?
A.Hawaii Department of Labor and Industrial Relations
B.Hawaii Department of Commerce and Consumer Affairs (DCCA)
C.Hawaii Department of Health
D.Hawaii Board of Electricians
Explanation: The Hawaii Department of Commerce and Consumer Affairs (DCCA) oversees contractor licensing through its Professional and Vocational Licensing Division. All specialty electrical contractors, including low voltage, are regulated by this agency.
2What type of license is required for low voltage electrical work in Hawaii?
A.General Electrician license
B.Specialty Electrician license
C.Master Electrician license
D.Apprentice Electrician license
Explanation: Hawaii requires a Specialty Electrician license for low voltage work. This includes categories for Journey Worker and Supervising Specialty Electrician, both regulated by the DCCA.
3According to NEC Article 725, what is the maximum voltage for a Class 2 circuit?
A.30 volts
B.42.4 volts peak
C.100 volts
D.150 volts
Explanation: NEC Article 725 limits Class 2 circuits to a maximum of 42.4 volts peak (or 30 volts for wet contact conditions). These limitations are designed to provide inherent protection against fire and electric shock.
4What NEC article covers fire alarm systems?
A.Article 700
B.Article 725
C.Article 760
D.Article 800
Explanation: NEC Article 760 covers the installation of fire alarm systems, including power-limited and non-power-limited circuits. It addresses wiring methods, cable types, and installation requirements specific to fire alarm systems.
5In Hawaii, what classification of specialty electrician can supervise low voltage work?
A.Journey Worker Specialty Electrician
B.Supervising Specialty Electrician
C.Apprentice Specialty Electrician
D.Limited Specialty Electrician
Explanation: In Hawaii, the Supervising Specialty Electrician classification has the authority to supervise low voltage electrical work. This level requires additional experience and examination beyond the Journey Worker level.
6What is the minimum bending radius for a Category 6 UTP cable?
A.1 inch
B.2 inches
C.4 times the cable diameter
D.10 times the cable diameter
Explanation: The minimum bending radius for Category 6 UTP cable is 4 times the cable's outer diameter. Exceeding this radius can cause signal degradation by deforming the internal wire pairs and affecting crosstalk performance.
7Which type of cable is required for fire alarm circuits in a plenum space?
A.CM (Communications Multipurpose)
B.CMP (Communications Multipurpose Plenum)
C.FPLP (Fire Power-Limited Plenum)
D.FPL (Fire Power-Limited)
Explanation: FPLP (Fire Power-Limited Plenum) cable is required for fire alarm circuits installed in plenum spaces. Plenum-rated cables have fire-retardant insulation that produces less smoke and toxic fumes when exposed to fire.
8What is the maximum pull tension for a standard 4-pair Cat 6 cable during installation?
A.10 lbf
B.25 lbf
C.50 lbf
D.100 lbf
Explanation: The maximum pull tension for a standard 4-pair Cat 6 cable is 25 pounds-force (lbf). Exceeding this tension can stretch the conductors and deform the cable geometry, leading to increased crosstalk and signal loss.
9According to the NEC, what is the minimum separation required between low voltage cables and power conductors in the same raceway?
A.No separation needed if both are insulated
B.Low voltage cables cannot share a raceway with power conductors unless listed for the purpose
C.2 inches minimum
D.6 inches minimum
Explanation: The NEC generally prohibits low voltage cables from sharing a raceway with power conductors unless specifically listed and identified for the purpose. This prevents electromagnetic interference and potential safety hazards from voltage differences.
10What is the primary purpose of a fire alarm control panel (FACP)?
A.To provide backup power during outages
B.To receive signals from detection devices and activate notification appliances
C.To suppress fires automatically
D.To monitor security cameras
Explanation: The fire alarm control panel (FACP) serves as the central hub that receives signals from detection devices like smoke detectors and pull stations, and activates notification appliances such as horns and strobes. It manages all fire alarm system functions and communicates with monitoring services.
