質問 # 56
According to NFPA 70, is the use of Teflon tape on threaded connections for conduits allowed?
正解：A
解説：
The correct answer isC. NFPA 70 requires thatmetal raceways and metal enclosures be metallically joined together into a continuous electrical conductor. This requirement is fundamental because threaded conduit systems are not only mechanical connections, but also part of theequipment grounding and bonding path.
Applying Teflon tape or similar nonconductive thread sealant to conduit threads can interfere with electrical continuity across the joint, which defeats the code intent for bonding and grounding.
From an API source inspection and quality surveillance perspective, the inspector must verify that conduit systems, fittings, and enclosures are assembled in a way that preserves electrical integrity, especially where grounding continuity is critical for personnel safety, fault-current return, and hazardous-location protection methods. The use of Teflon tape is therefore not accepted as a general practice on threaded conduit connections because it can compromise the metallic path. Option A is incorrect because the rule is not limited to Class I, Division 2. Option B is incorrect because water exclusion does not override bonding requirements.
Option D is also incorrect because Teflon tape does not create an approved explosion-proof vapor seal.
質問 # 57
According to ANSI C57.12, the average winding temperature rise above ambient temperature shall not exceed what value?
正解：B
解説：
The correct answer isA. UnderANSI C57.12transformer requirements, theaverage winding temperature rise above ambientis commonly limited to65°Cfor standard transformer designs. This limit is important because transformer insulation life is strongly affected by operating temperature. If the winding temperature rise exceeds the permitted value, insulation aging accelerates, reducing transformer reliability and service life.
That is why temperature-rise testing is a key verification item during transformer manufacture and factory acceptance activities.
From a source inspection perspective, the inspector should verify that the transformer has been tested in accordance with the applicable standard, that the measured temperature-rise values are properly recorded, and that the results comply with the specified acceptance criteria. The average winding temperature rise is not the same as hotspot temperature, and it must be evaluated against the standard test method and rating basis. The other options are too high for the standard average winding rise value typically associated with ANSI C57.12.
In API-aligned source inspection and quality surveillance oftransformers, confirming compliance of factory test results such as temperature-rise performance is an essential part of final acceptance. Therefore,65°Cis the verified answer.
質問 # 58
Deviations from specifications must be approved by the:
正解：D
解説：
The correct answer isDbecause anydeviation from the approved specification, code requirement, purchase document, or design basismust be formally accepted by theresponsible engineer, not simply by manufacturing, quality, or inspection personnel. In source inspection practice, the manufacturer's engineer may identify or propose a deviation, and the vendor's quality manager may document it within the nonconformance system, but neither of them has final authority to approve a change that affects design intent, technical compliance, or purchaser requirements. The inspection coordinator also manages logistics and communication, but is not the technical approval authority.
This is a fundamental principle in API-aligned source inspection and surveillance. The source inspector verifies conformance to the approved drawings, specifications, and referenced standards. When a deviation is found, it must be handled through the formal deviation or concession process and resolved by the party with technical design responsibility. That is why theresponsible engineeris the correct approving authority. This preserves engineering accountability, maintains traceability, and ensures that any departure from specification is technically evaluated before acceptance. Therefore,option Dis the verified answer.
質問 # 59
This device is a(n):
正解：A
解説：
The correct answer isAbecause the illustrated device is anoutside micrometer. Its labeled parts clearly identify it:frame, anvil, spindle, lock nut, thimble, and ratchet knob. These are the standard components of a micrometer used for highly accurate dimensional measurement of outside diameters, thicknesses, and small gaps. In source inspection and quality surveillance, this type of instrument is commonly used when verifying critical dimensions of machined parts, shaft diameters, plate thicknesses, and other precision features that must comply with drawings and manufacturing tolerances.
The other options do not match the image. Adigital caliperhas sliding jaws and an electronic display. Avernier caliperalso uses sliding jaws with a vernier scale, not a rotating thimble and spindle arrangement. Anengineer' s scaleis a straight rule used for scaled drawing measurements, not for precision mechanical inspection. In API-aligned source inspection practice, understanding inspection tools is essential because inspectors must use the correct measuring instrument for the required tolerance and ensure that the device is properly controlled and calibrated. Therefore, the pictured instrument is correctly identified as amicrometer, makingoption Athe verified answer.
質問 # 60
The highest voltage rating on a piece of medium voltage equipment is the:
正解：D
解説：
The correct answer isA, basic impulse level. On medium voltage equipment, thebasic impulse level BILis the highest voltage-related rating normally associated with the insulation system. BIL represents the ability of the equipment insulation to withstand a specified high-voltage impulse, such as a lightning surge or switching surge, without failure. It is therefore a dielectric withstand rating that is higher than the equipment's normal operating or system voltage and is used to define insulation coordination for the equipment.
The other choices are not the best answer.Nominal voltageidentifies the intended system operating voltage class, but it is not the highest voltage-related rating.AC high potentialandDC high potentialare test voltages used during dielectric testing, not the principal nameplate rating that defines the equipment's insulation impulse withstand capability. In source inspection of switchgear and other medium voltage assemblies, the inspector verifies that the equipment ratings, including voltage class, insulation level, and test records, agree with the purchase specification and applicable standards.
Because BIL expresses the highest recognized insulation withstand rating among the listed options,Ais the verified answer.
