問題 #83
According to NFPA 70, equipment shall be marked to show the hazardous environment for which it has been evaluated. Markings on this equipment shall include which of the following?
答案：B
解題說明：
The correct answer isB. For equipment intended for hazardous locations,NFPA 70requires marking that identifies the hazardous environment for which the equipment has been evaluated. Those markings must communicate the essential classification information needed for safe application in the field. This includes theClassof hazardous location, theDivisionwhere applicable, thematerial classification group, theequipment temperatureor temperature code, and theambient temperature rangewhen relevant. These markings allow the user, inspector, and installer to confirm that the equipment is suitable for the specific flammable gas, vapor, dust, or fiber hazard present at the site.
From an API source inspection perspective, this is a critical verification item during final inspection because hazardous-area suitability depends not only on construction, but also on propernameplate and marking compliance. The inspector must confirm that the marked classification agrees with the purchase specification, area classification documents, and certification data. Options A, C, and D are incorrect becausevoltage, current, andmaterial of constructionare not the specific hazardous-location marking elements asked for here.
The required hazardous-environment marking set is most accurately described inB.
問題 #84
According to ANSI/NETA/ATS, when performing a dielectric withstand test on each bus section, the test voltage shall be applied for how long?
答案：A
解題說明：
The correct answer isB. UnderANSI/NETA/ATSpractices, adielectric withstand teston eachbus sectionis typically performed by applying the specified test voltage forone minute. This one-minute duration is the standard acceptance interval used to demonstrate that the bus insulation system can safely withstand the prescribed overvoltage without breakdown, flashover, or unacceptable leakage. It provides enough time to reveal insulation weakness while remaining within the intended non-routine high-potential test method for acceptance testing.
From a source inspection perspective, this matters because switchgear bus insulation integrity is a critical verification point during factory testing and final quality surveillance. The inspector is expected to confirm that the correct test method, voltage level, duration, and acceptance criteria are used and properly recorded in the manufacturer's test documentation. The API Guide for Source Inspection and Quality Surveillance of Electrical Equipment includesswitchgearsamong the major covered equipment categories and emphasizes verification of tests, records, and compliance with applicable standards during source inspection and surveillance. Therefore, for a dielectric withstand test on each bus section, the specified voltage is applied forone minute, makingoption Bthe verified answer.
問題 #85
Metallic shielding components such as tapes, wires, or braids shall be connected to a:
答案：D
解題說明：
The correct answer isA. Metallic shielding components in cables, such asshield tapes, drain wires, metallic braids, or similar conductive shielding layers, are connected to theequipment grounding system, commonly through anequipment grounding busbaror other approved grounding termination point. The purpose of this connection is to provide a low-impedance path for induced voltages, capacitive charging current, noise, and fault-related currents, while also helping reduce electromagnetic interference and maintaining personnel safety.
In source inspection and quality surveillance of electrical systems, correct shield termination is important because improper grounding can lead to noise problems, unreliable signal performance, unsafe touch potentials, or ineffective fault-current control. The inspector therefore checks that cable shields and associated metallic components are terminated in accordance with the approved drawings, cable schedules, and project grounding requirements.
The other options are incorrect. Aceramic insulatordoes not provide the required grounding path. Alow voltage connectoris too generic and is not the intended grounding termination. Atransformer center tapis a system neutral point, not the correct destination for cable metallic shielding. Therefore, the proper connection point is theequipment grounding busbar.
問題 #86
Deviations from specifications must be approved by the:
答案：A
解題說明：
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.
問題 #87
According to API 541, the combined runout for areas on the shaft that are to be observed by radial vibration probes shall not exceed:
答案：B
解題說明：
The correct answer isD. In API 541, when a motor shaft is monitored usingradial vibration probes, the probe- observed shaft surface must meet a strictcombined runoutlimit so that the vibration reading reflects actual machine vibration rather than shaft surface irregularity, eccentricity, or electrical and mechanical runout effects. API 541 sets this limit at25% of the allowed unfiltered peak-to-peak vibration amplitude or 6.4 µm
0.25 mils, whichever is greater. This requirement is important because excessive runout can distort probe signals and produce misleading vibration data during shop testing and acceptance.
From a source inspection standpoint, this is a critical verification item during motor testing for large rotating equipment. If the shaft finish and probe track are not within the required runout limit, the vibration measurements cannot be relied on for acceptance decisions. The API guide includeselectric motors over 500 HPas a covered equipment category and emphasizes inspection and surveillance activities tied to applicable standards, testing, and verification of compliance during manufacture. Therefore,option Dis the correct API
541 requirement.
