1. The primary role of an API SIEE Source Inspector is to:
A. Design electrical equipment
B. Inspect electrical equipment during fabrication and testing
C. Perform field installation
D. Approve electrical drawings for construction
ANSWER : B
Explanation:
A Source Inspector verifies that electrical equipment meets applicable codes,
standards, and purchase specifications during manufacturing and testing—not
design or installation.
2. Which standard is most commonly referenced for hazardous area
electrical equipment?
A. IEEE 519
B. NEC (NFPA 70)
C. ASME Section VIII
D. ISO 9001
ANSWER : B
Explanation:
The National Electrical Code (NEC/NFPA 70) governs hazardous (classified)
locations and electrical equipment requirements.
3. Explosion-proof equipment is primarily designed to:
A. Prevent sparks
B. Withstand internal explosions without igniting external atmosphere
,C. Eliminate heat
D. Reduce electrical load
ANSWER : B
Explanation:
Explosion-proof enclosures contain internal explosions and prevent ignition of
surrounding hazardous atmospheres.
4. Which NEC article covers hazardous (classified) locations?
A. Article 100
B. Article 110
C. Article 500
D. Article 725
ANSWER : C
Explanation:
NEC Articles 500–505 address hazardous (classified) locations and associated
equipment requirements.
5. What is the primary purpose of a Factory Acceptance Test (FAT)?
A. Verify field installation
B. Validate equipment performance before shipment
C. Confirm site readiness
D. Train operators
ANSWER : B
Explanation:
FAT ensures equipment complies with specifications and functions correctly
before leaving the manufacturer.
6. Which document defines inspection hold points and witness points?
A. Bill of Materials
B. Inspection and Test Plan (ITP)
,C. Wiring diagram
D. Data sheet
ANSWER : B
Explanation:
The ITP specifies when inspections must stop (hold) or be observed (witness)
during fabrication.
7. A “hold point” means work:
A. May proceed without inspection
B. Must stop until inspection approval
C. Is optional
D. Is documented only
ANSWER : B
Explanation:
Hold points require inspector approval before work continues.
8. Which enclosure rating protects against dust and water immersion?
A. NEMA 1
B. NEMA 3R
C. NEMA 4X
D. NEMA 12
ANSWER : C
Explanation:
NEMA 4X enclosures protect against dust, water spray, and corrosion.
9. The purpose of grounding electrical equipment is to:
A. Increase voltage
B. Improve efficiency
C. Protect personnel and equipment
D. Reduce current
, ANSWER : C
Explanation:
Grounding provides a safe path for fault current, preventing electric shock and
equipment damage.
10. Which test verifies insulation resistance?
A. Continuity test
B. Megger test
C. Load test
D. Hi-pot test
ANSWER : B
Explanation:
A megger test measures insulation resistance to detect degradation or moisture.
11. Hi-pot testing is primarily used to:
A. Measure resistance
B. Verify dielectric strength
C. Check polarity
D. Test grounding continuity
ANSWER : B
Explanation:
Hi-pot testing confirms insulation can withstand high voltage without
breakdown.
12. What document specifies voltage, current, and enclosure requirements?
A. Inspection report
B. Purchase order
C. Equipment data sheet
D. NCR
ANSWER : C
A. Design electrical equipment
B. Inspect electrical equipment during fabrication and testing
