Explanation: NEC 2023 Article 210.8(A) expanded GFCI requirements to include 250-volt receptacles (such as those for electric dryers and ranges) in bathrooms, basements, garages, outdoors, kitchens, and laundry areas. This is a significant change from NEC 2020 which only required GFCI for 125V receptacles.

4Per NEC 2023 Article 230.67, surge protection is now required for dwelling unit services. What type of surge protective device is mandated?

A.Type 3 SPD only

B.Type 1 or Type 2 surge protective device (SPD)

5Per NEC 2023 Article 210.8(A), GFCI protection is required for 125-volt, 15- and 20-ampere receptacles in dwelling unit bathrooms. What is the trip threshold for a Class A GFCI?

A.4-6 milliamperes

B.10 milliamperes

C.15 milliamperes

D.30 milliamperes

Explanation: A Class A GFCI device trips at 4-6 milliamperes of ground-fault current. This low threshold provides effective protection against electric shock in wet locations like bathrooms per NEC Article 210.8(A).

6Per NEC 2023 Article 250.52(A)(1), a metal underground water pipe used as a grounding electrode must be in direct contact with the earth for at least:

A.5 feet

B.8 feet

C.10 feet

D.15 feet

Explanation: Per NEC 2023 Article 250.52(A)(1), a metal underground water pipe in direct contact with the earth for 10 feet or more qualifies as a grounding electrode. This ensures adequate ground contact for effective grounding.

7Per NEC 2023 Table 310.16, what is the ampacity of a 10 AWG copper conductor with THHN insulation at 30°C?

A.30 amperes

B.35 amperes

C.40 amperes

D.45 amperes

Explanation: Per NEC 2023 Table 310.16, a 10 AWG copper conductor with THHN insulation (90°C column) has an ampacity of 40 amperes at 30°C ambient temperature.

8Per NEC 2023 Article 430.52, what is the maximum dual-element time-delay fuse size for a single motor branch circuit, expressed as a percentage of motor FLC?

A.125%

B.150%

C.175%

D.250%

Explanation: Per NEC 2023 Table 430.52, the maximum rating for a dual-element time-delay fuse for a single motor is 175% of the motor full-load current. If this value does not correspond to a standard fuse size, the next higher standard size may be used.

9Per NEC 2023 Article 210.52(A), receptacles in habitable rooms of dwelling units must be spaced so no point along the floor line is more than how far from a receptacle?

A.4 feet

B.6 feet

C.8 feet

D.12 feet

Explanation: Per NEC 2023 Article 210.52(A)(1), receptacle outlets must be installed so that no point along the floor line in any wall space is more than 6 feet, measured horizontally, from a receptacle outlet.

10Per NEC 2023 Article 220.12, the general lighting load for a dwelling unit is calculated at:

A.2 VA per square foot

B.3 VA per square foot

C.3.5 VA per square foot

D.5 VA per square foot

Explanation: Per NEC 2023 Table 220.12, dwelling units use 3 volt-amperes per square foot for general lighting load calculations. This value is the starting point for both the standard and optional calculation methods.
