1. What is the minimum working space depth required in front of electrical equipment rated
150 A or less with exposed live parts on one side and grounded parts on the other?
A) 24 inches
B) 30 inches
C) 36 inches
D) 42 inches
Correct Answer: C
Rationale: NEC 110.26(A)(1) requires a working space depth of 3 feet (36 inches) for equipment
rated 0-150 volts, provided there are exposed live parts on one side and grounded parts on the
other. This applies to most residential and light commercial equipment installations .
2. Which NEC article establishes the general requirements for working space around electrical
equipment?
A) Article 100
B) Article 110
C) Article 210
D) Article 300
Correct Answer: B
, Page 3 of 122
Rationale: Article 110 of the NEC sets the general requirements for workspace, clearances,
accessibility, and identification for electrical equipment. This article is fundamental for safe
installation and maintenance access .
3. According to NEC 110.3(B), how must listed equipment be installed?
A) According to local inspector preferences
B) According to its listing and manufacturer instructions
C) In any manner that is cost-effective
D) According to the builder's specifications
Correct Answer: B
Rationale: NEC 110.3(B) mandates that listed or labeled equipment must be installed and used
in accordance with its listing and any instructions included in the listing. This makes
manufacturer instructions enforceable code requirements .
4. What is the minimum headroom required for working spaces around electrical equipment
per NEC 110.26(A)(3)?
A) 6 feet
B) 6 feet 6 inches or the height of the equipment, whichever is greater
C) 7 feet
D) 8 feet

Correct Answer: B
Rationale: NEC 110.26(A)(3) requires minimum headroom of 6 feet 6 inches or the height of the
equipment, whichever is greater, for working spaces around electrical equipment .
5. According to NEC 110.12, what general requirement applies to all electrical equipment
installation?
A) Equipment must be painted to match the building
B) Equipment must be installed in a neat and workmanlike manner
C) All wiring must be concealed
D) Equipment must be labeled with installer information
Correct Answer: B
Rationale: NEC 110.12 requires that electrical equipment be installed in a neat and workmanlike
manner. This is a general quality standard enforced by inspectors .
6. According to NEC 110.14(C)(1), what temperature rating governs conductor terminations on
equipment rated 100 A or less?
A) 60°C unless both the conductor and equipment are listed for a higher temperature
B) 75°C is the standard for all terminations
C) 90°C to maximize conductor ampacity
D) The conductor temperature rating always governs
