Covering NEC, Grounding,
Overcurrent Protection & Inspection
Procedures (2025/2026) With
Verified Answers
1. What is the primary purpose of the National Electrical Code
(NEC)?
• A) To regulate building codes for structural safety
• B) To establish safety standards for electrical installations and
wiring
• C) To provide guidelines for plumbing systems
• D) To set environmental protection standards
Answer: B
Rationale: The NEC is designed to safeguard persons and property from
electrical hazards.
2. Which article of the NEC defines the term "readily accessible"?
• A) Article 100
• B) Article 110
• C) Article 210
• D) Article 310
Answer: A
Rationale: Article 100 contains the definitions for key NEC terminology.
,3. The right of entry for an electrical inspector is primarily based on
which of the following?
• A) State building code
• B) NEC 110.2(A)
• C) Local fire code
• D) OSHA regulations
Answer: B
Rationale: NEC 110.2(A) grants authorized inspectors the right to enter
premises to perform inspections and enforce the code.
4. Which Florida Statute authorizes the certification of Electrical
Plans Examiners and Inspectors?
• A) F.S. 468.001
• B) F.S. 553.021
• C) F.S. 553.05
• D) F.S. 468.015
Answer: A
Rationale: Florida Statute 468 governs the licensing and certification of
electrical professionals.
5. When reviewing a permit application, the inspector must verify
that the contractor holds which type of license?
• A) General contractor license
• B) Master electrician license
• C) Plumbing license
• D) HVAC license
,Answer: B
Rationale: Only a master electrician or equivalent licensed individual
may perform electrical work.
6. In a commercial electrical room, what is the minimum working
space clearance in front of equipment rated 600V or less?
• A) 24 in. wide and 30 in. deep
• B) 30 in. wide and 36 in. deep
• C) 36 in. wide and 42 in. deep
• D) 42 in. wide and 48 in. deep
Answer: B
Rationale: NEC 110.26(A)(1) requires a clear working space of at least 30
inches wide and 36 inches deep.
7. The rating of a service disconnect must be at least:
• A) 125% of the calculated load
• B) 100% of the calculated load
• C) 150% of the calculated load
• D) 175% of the calculated load
Answer: A
Rationale: NEC 230.42 requires the service disconnect rating to be not
less than 125% of the calculated load.
8. What is the main purpose of grounding in electrical systems?
• A) To complete the circuit
, • B) To provide a safe path for fault currents and prevent electric
shock
• C) To increase voltage levels
• D) To reduce power consumption
Answer: B
Rationale: Grounding provides a safe path for fault currents, helping to
protect people and equipment from electrical shock.
9. During inspection of a commercial panelboard, an inspector finds
multiple neutrals and grounds terminated under the same terminal
screw in a subpanel. What is the main issue?
• A) This improves fault current return
• B) It reduces voltage drop in circuits
• C) Neutrals and grounds must be isolated in subpanels
• D) It is required for multiwire branch circuits
Answer: C
Rationale: Neutrals and equipment grounding conductors must be
separated in subpanels to prevent objectionable current on grounding
paths.
10. What is the main reason for installing arc-fault circuit
interrupters (AFCIs)?
• A) To prevent overcurrent in appliances
• B) To reduce the risk of electrical fires caused by arc faults
• C) To protect against ground faults
• D) To regulate voltage in circuits
Answer: B
Rationale: AFCIs detect arcing conditions that could lead to electrical
fires and disconnect power to prevent hazards.
