Florida Electrical Journeyman Examination
Question 1
Which National Electrical Code requirement primarily exists to ensure that
electrical installations minimize fire and shock hazards while promoting safe and
reliable system operation?
,A. To reduce construction costs regardless of installation quality
B. To establish minimum safety standards for electrical installations
C. To replace all local electrical inspection requirements
D. To eliminate the need for qualified electricians
Answer: B
Rationale: The NEC establishes minimum safety standards intended to protect
people and property from electrical hazards. It is not a design manual or cost-
saving document.
Question 2
When applying Ohm's Law during troubleshooting, what current flows through a
resistance of 20 ohms connected across a 240-volt electrical source?
A. 8 A
B. 10 A
C. 12 A
D. 20 A
Answer: C
Rationale: Current = Voltage ÷ Resistance = 240 ÷ 20 = 12 amperes.
Question 3
Why is equipment grounding considered essential for electrical systems installed
in residential, commercial, and industrial buildings throughout Florida?
A. It increases operating voltage
B. It provides a low-impedance path for fault current
C. It eliminates the need for circuit breakers
D. It prevents voltage drop during normal operation
,Answer: B
Rationale: Equipment grounding provides a low-resistance fault-current path,
allowing overcurrent devices to open quickly during faults.
Question 4
Which conductor insulation type is commonly approved for use in dry and wet
locations and frequently installed inside conduit systems?
A. THHN/THWN-2
B. NM cable only
C. Lamp cord
D. Speaker wire
Answer: A
Rationale: THHN/THWN-2 conductors are widely used because they are rated for
both dry and wet locations.
Question 5
When sizing branch-circuit conductors supplying a continuous electrical load, how
should the conductor ampacity generally be determined according to the NEC?
A. 80% of load current
B. Equal to load current
C. 125% of continuous load
D. 50% of continuous load
Answer: C
Rationale: Continuous loads require conductors sized for 125% of the continuous
load unless otherwise permitted by the NEC.
, Question 6
Which instrument should an electrician use when accurately measuring electrical
resistance after verifying that a circuit has been completely de-energized?
A. Clamp ammeter
B. Ohmmeter
C. Wattmeter
D. Megaphone
Answer: B
Rationale: An ohmmeter measures resistance and should only be used on de-
energized circuits.
Question 7
What is the primary purpose of an overcurrent protective device installed in an
electrical distribution system?
A. Increase voltage output
B. Protect conductors and equipment from excessive current
C. Improve power factor
D. Reduce conductor resistance
Answer: B
Rationale: Circuit breakers and fuses protect conductors and equipment from
overloads and short circuits.
Question 8
When installing EMT conduit, why must it be securely supported according to NEC
requirements?
