Board can impose for a single violation of contracting without a license?
A. $5,000
B. $15,000
C. $10,000
D. $25,000
Answer: C
Conceptual Explanation: According to NRS 624.710, the Board may impose an
administrative fine of not less than $1,000 and not more than $10,000 for each violation of
contracting without a license.
2. According to NEC 250.66, what is the minimum size of a copper Grounding Electrode
Conductor for a service with 4/0 AWG copper service-entrance conductors?
A. 4 AWG
B. 2/0 AWG
C. 1/0 AWG
,D. 2 AWG
Answer: D
Conceptual Explanation: Table 250.66 specifies that for copper service conductors of 3/0
through 250 kcmil, the minimum size copper GEC is 2 AWG.
3. In a Nevada C-2 context, how many days does a contractor have to notify the Board of a
change in the name of the business entity?
A. 10 days
B. 30 days
C. 15 days
D. 45 days
Answer: B
Conceptual Explanation: NAC 624.640 requires a licensee to notify the Board in writing
within 30 days of any change to the name or address of the business.
4. When calculating motor branch-circuit short-circuit and ground-fault protection for a single
15 HP, 230V, three-phase squirrel-cage motor using an inverse time breaker, what is the
maximum rating permitted?
A. 80 Amps
B. 100 Amps
C. 110 Amps
, D. 125 Amps
Answer: C
Conceptual Explanation: FLC from Table 430.250 is 42A. 430.52(C)(1) allows 250% for
inverse time breakers. 42 * 2.5 = 105A. Exception No. 1 allows the next standard size up,
which is 110A according to 240.6.

Answer: D
Conceptual Explanation: Per Annex C, Table C.1, for 3/4 inch EMT and 12 AWG THHN, the
maximum number of conductors is 16.
6. A 240-volt single-phase circuit has a total resistance of 8 ohms. What is the power
consumed by this circuit in Watts?
A. 3,200 W
B. 7,200 W
C. 1,920 W
