QUESTION 1
According to API 541, during a witness or observed test of a 500 hp (375 kW) induction
motor, the purchaser shall have the right to observe all the following, which may occur
due to the expected or unexpected part or event of the test except:
A) Dismantling of the motor
B) Inspection of the motor
C) Disassembly of the rotor
D) Reassembly of the motor
Correct Answer: C
Explanation: Under API 541 witness testing, the purchaser has the right to observe motor-
level activities including dismantling, inspection, and reassembly. However, "disassembly
of the rotor" itself is not a standard purchaser observation right described in the same way.
This distinction is important for source inspectors who must recognize observation
boundaries during standard test observation .
QUESTION 2
According to IEEE 841, terminal boxes for voltages above 1000 V or for frame sizes
exceeding 449T at 1000 V shall be provided with:
A) A drain fitting
B) A permanent locking mechanism
C) Grounding provisions
D) An explosion-proof seal
Correct Answer: B
Explanation: IEEE 841 requires a permanent locking mechanism for medium-voltage
motor terminal boxes above 1000 V and for certain large frame motors at 1000 V. This
,added safety provision prevents unauthorized or accidental access while the motor is
energized, supporting safe operation and maintenance control .
QUESTION 3
What method is used to verify tightness of accessible bolted electrical connections?
A) Compression of the lock-nut
B) Visual inspection of torque markings
C) Verification of an assembly check sheet
D) Calibrated torque wrench
Correct Answer: D
Explanation: A properly calibrated torque wrench is the accepted method to verify
tightness of accessible bolted electrical connections. Proper torque is critical because
under-tightening can cause high resistance and localized heating, while over-tightening
can damage threads or connectors .
QUESTION 4
Who should the Source Inspector notify if they believe that product quality may be
compromised by schedule pressures?
A) The Master Scheduler
B) The Inspection Coordinator
C) The shop QA Manager
D) The Project Manager
Correct Answer: B
Explanation: The inspector's role is to independently communicate quality-related
concerns through the established inspection reporting chain. When schedule pressure
appears likely to compromise quality, the issue must be escalated to the inspection
coordinator, who manages inspection execution and communication between purchaser,
supplier, and inspection function .
,QUESTION 5
Which document provides the official list of topics included in the API SIEE exam?
A) The ASME Boiler Code
B) The Body of Knowledge
C) The ISO 9001 Standard
D) The NEC Handbook
Correct Answer: B
Explanation: API provides a Body of Knowledge document that lists the specific topics
included in the API SIEE exam. This document serves as the official guide for candidates
preparing for the certification examination .
QUESTION 6
What types of electrical equipment are covered under API SIEE inspection?
A) Only wiring and conduit
B) Only lighting fixtures
C) Junction boxes, control panels, transformers, switchgear, motor control centers, and
electric motors (over 500 HP)
D) Only generators and turbines
Correct Answer: C
Explanation: API SIEE covers inspection of electrical material and equipment including
junction boxes, control panels, electrical systems, transformers, switchgear, motor control
centers, and electric motors (over 500 HP) .
QUESTION 7
According to API 541, subsequent to completion of manufacture and testing, the vendor
shall revise and resubmit the previously supplied purchase data including all the
following except:
A) Rotor-balance report
B) Operating manual
C) As-built data sheet
D) Shop test data
, Correct Answer: A
Explanation: Under API 541, the final turnover package includes the operating manual, as-
built data sheet, and shop test data. A rotor-balance report, while important as an internal
manufacturing record, is not typically identified as part of the formal purchaser data
resubmittal package .
QUESTION 8
What is the duration of the API SIEE exam?
A) 2 hours
B) 3.25 hours
C) 4 hours
D) 5 hours
Correct Answer: B
Explanation: The API SIEE exam is 3.25 hours long. It consists of 110 questions, of which
only 100 are scored. The remaining 10 are pretest questions that are not scored .
QUESTION 9
For how long is the API SIEE certification valid?
A) 1 year
B) 2 years
C) 3 years
D) 5 years
Correct Answer: C
Explanation: The API SIEE certification is valid for a three-year term. Inspectors are
required to apply for recertification every three years .
QUESTION 10
What is the primary purpose of the API SIEE certification?
A) To certify electrical engineers for design work
B) To qualify individuals for quality surveillance of electrical equipment at
