API Source Inspector Electrical Equipment 認定 API-SIEE 試験問題 (Q68-Q73):

質問 # 68
What is an advantage of the Insulation Resistance test?

正解：D

解説：
The correct answer isAbecause theinsulation resistance testis fundamentally anon-destructivediagnostic test when performed at the proper test voltage and in accordance with accepted procedures. It is used to evaluate the condition of insulation by applying a DC test voltage that iswell below the insulation breakdown leveland measuring the resistance to leakage current. This allows the inspector or tester to assess insulation health without intentionally damaging the equipment. That is why it is commonly used during factory testing, pre- commissioning checks, maintenance evaluations, and source inspection verification activities.
The other options are incorrect.Moisturesignificantly affects insulation resistance and usually lowers the measured value.Temperaturealso affects readings, which is why test results are often corrected or interpreted with temperature in mind. The test isnotintended to be conducted above the breakdown voltage of the insulation; doing so would be destructive and would belong to a different category of high-potential testing.
The API Guide for Source Inspection and Quality Surveillance of Electrical Equipment includeselectrical systemsamong the covered equipment categories and focuses onsource inspection and quality surveillance activitiesused to verify conformance and test readiness.


質問 # 69
What requirement shall be included in a lockout/tagout procedure?

正解：B


質問 # 70
According to IEEE 841, terminal boxes for voltages above 1000 V or for frame sizes exceeding 449T at 1000 V shall be provided with:

正解：D

解説：
The correct answer isB. Formedium-voltage motor terminal boxes, IEEE 841 requires an added safety provision because these enclosures contain higher-energy terminations and present a more serious shock and arc-flash hazard than standard low-voltage terminal boxes. Apermanent locking mechanismis therefore required for terminal boxes used on motors above1000 V, and also for certain large frame motors at1000 V, to prevent unauthorized or accidental access while the motor is energized. This requirement supports safe operation, maintenance control, and electrical isolation practices.
From an API source-inspection perspective, this falls under verification ofelectrical safety features, enclosure construction, and compliance with the applicable motor standardduring shop inspection and surveillance. The API guide includeselectric motors over 500 HPamong the covered equipment categories and emphasizes checking conformance to applicable codes, referenced standards, drawings, and purchase specifications during manufacture and inspection. A drain fitting may be required on some terminal boxes for moisture control, and grounding provisions are also important, but those are not the specific IEEE 841 requirement identified in this question. The distinctive requirement here is thepermanent locking mechanism.


質問 # 71
According to NFPA 70, is the use of Teflon tape on threaded connections for conduits allowed?

正解：B

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 # 72
When might a resident source inspector be required at a shop during manufacture and fabrication?

正解：A

解説：
The correct answer isA. In API source inspection practice, the decision to assign aresident source inspectoris driven primarily by therisk level of the equipment or fabrication activity. When the risk assessment identifies an item ashigh or highest risk, increased surveillance may be necessary because the consequences of defects, missed hold points, schedule slippage, or nonconformance can be significant. A resident inspector provides continuous or frequent monitoring of manufacturing progress, verification of critical stages, review of records, and immediate reporting of issues that could affect quality, cost, or delivery.
Option B is not sufficient by itself. Being sourced from a foreign vendor may affect logistics or planning, but it does not automatically justify a resident inspector. Option C is based on convenience, not inspection need.
Option D may create project pressure, but a busy shop or tight schedule alone is not the primary criterion for resident assignment.
The API approach is risk-based: surveillance intensity, including the possible need for a resident inspector, is determined by thecriticality and risk classificationof the equipment and the potential impact of nonconformance during manufacture.
