Verified Exam
1. A 120V branch circuit supplies a continuous load of 14 amps. What is the
minimum rating of the circuit conductors?
A. 14A
B. 15A
C. 20A
D. 25A
Correct Answer: C ✔ (20A)
The NEC requires continuous loads to be calculated at 125% of the load; 14A ×
1.25 = 17.5A, so the next standard conductor/circuit size is 20A.
2. According to NEC, what is the maximum number of 12 AWG copper
conductors allowed in a 3/4-inch EMT conduit?
A. 7
B. 10
C. 15
D. 20
Correct Answer: B ✔ (10)
Conduit fill rules under NEC Chapter 9 allow 40% fill for more than two
conductors, and 3/4-inch EMT typically accommodates up to 10 conductors of 12
AWG.
3. A grounding electrode conductor must be sized based on which of the
following?
, A. Service entrance conductor size
B. Breaker rating
C. Load current
D. Motor horsepower
Correct Answer: A ✔ (Service entrance conductor size)
NEC Table 250.66 requires GEC sizing based on the size of the largest
ungrounded service-entrance conductor.
4. What is the minimum burial depth for a PVC conduit carrying 120V
residential branch circuits under a driveway?
A. 6 inches
B. 12 inches
C. 18 inches
D. 24 inches
Correct Answer: D ✔ (24 inches)
NEC Table 300.5 requires 24 inches of cover for residential branch circuits under
driveways using PVC conduit.
5. A 240V single-phase load draws 24 amps. What is the minimum circuit
breaker size?
A. 20A
B. 25A
C. 30A
D. 40A
Correct Answer: C ✔ (30A)
Breaker sizing must follow the next standard rating above load; 24A requires a
30A breaker.
6. Which device is required for personnel protection in bathroom receptacles?
A. AFCI
B. GFCI
C. Fuse
D. Disconnect switch
, Correct Answer: B ✔ (GFCI)
NEC 210.8 requires GFCI protection in bathroom receptacle outlets for shock
protection.
7. What is the allowable voltage drop recommendation for branch circuits?
A. 1%
B. 3%
C. 5%
D. 10%
Correct Answer: B ✔ (3%)
NEC recommends a maximum 3% voltage drop on branch circuits for efficient
operation.
8. A 20A, 120V circuit supplies 1,800 watts of lighting. Is the load acceptable?
A. Yes
B. No
C. Only if continuous
D. Only if grounded
Correct Answer: A ✔ (Yes)
1800W ÷ 120V = 15A, which is within the 20A circuit limit.
9. Which conductor type is required for wet locations?
A. THHN only
B. THW only
C. THWN or THWN-2
D. NM cable
Correct Answer: C ✔ (THWN or THWN-2)
THWN insulation is rated for wet locations per NEC conductor listing rules.
10.What is the minimum size copper equipment grounding conductor for a
60A circuit?
A. 14 AWG
B. 12 AWG
