Sample E2 Commercial Electrical Inspector Practice Questions
Try these questions from our free E2 Commercial Electrical Inspector practice tests. The correct answer and an explanation follow each question.
An inspector observes a 40-foot continuous run of 1-inch Electrical Metallic Tubing (EMT) installed exposed on a commercial warehouse wall. What are the maximum permitted spacing requirements for securing and supporting this raceway according to NEC Article 358?
- A. Within 5 feet of each box and every 10 feet thereafter.
- B. Within 3 feet of each box and every 12 feet thereafter.
- C. Within 3 feet of each box and every 10 feet thereafter.
- D. Within 18 inches of each box and every 8 feet thereafter.
Answer: C. Within 3 feet of each box and every 10 feet thereafter.
NEC 358.30(A) requires that EMT be securely fastened in place at least every 10 feet. Additionally, NEC 358.30(B) mandates that EMT must be securely fastened within 3 feet of each outlet box, junction box, device box, cabinet, or conduit body.
During a plan review for a commercial building, the inspector notices that the electrical drawings lack a fault current calculation. What should the inspector require before approving the plans?
- A. Approve the plans and note the deficiency for field inspection
- B. Require the engineer to provide available fault current calculations and equipment interrupting ratings
- C. Accept the plans if the equipment is listed by a nationally recognized testing laboratory
- D. Request only the load calculations since fault current is determined in the field
Answer: B. Require the engineer to provide available fault current calculations and equipment interrupting ratings
NEC 110.9 and 110.10 require that equipment have adequate interrupting ratings and be protected against fault currents, which must be verified during plan review.
A commercial electrical inspector finds a 600A, 480V panelboard installed in a boiler room with ambient temperatures regularly reaching 45°C. What is the primary concern?
- A. Overcurrent devices are rated at 40°C; derating is required above that temperature
- B. All panelboards are rated for up to 75°C ambient without derating
- C. The breakers must be replaced with fuses at elevated temperatures
- D. Only service entrance equipment requires temperature derating
Answer: A. Overcurrent devices are rated at 40°C; derating is required above that temperature
Most overcurrent protective devices are rated at 40°C ambient; sustained higher temperatures require derating per manufacturer specifications and NEC guidelines.
An electrical inspector is examining a new installation in a commercial building. Which of the following defines the term 'Approved' as used in the NEC?
- A. Listed by a qualified electrical testing laboratory
- B. Meeting the manufacturer's specifications
- C. Acceptable to the authority having jurisdiction (AHJ)
- D. In compliance with all local building codes
Answer: C. Acceptable to the authority having jurisdiction (AHJ)
NEC Article 100 defines 'Approved' as 'acceptable to the authority having jurisdiction.' While listing and compliance with other codes are important considerations for the AHJ, the final approval rests with them.
