API-SIEE Exam Dumps - API ICP Programs Questions and Answers

The correct answer isD. In rotating electrical equipment,non-contacting probesnormally refer toproximity probesthat are mounted in or at thebearing housingsto monitorshaft relative vibration. These probes do not touch the shaft; instead, they sense shaft motion relative to the bearing housing. In practice, radial vibration is usually monitored in thehorizontal and vertical directions, and where applicable axial movement is also monitored using an axial probe arrangement. That makes option D the only technically correct choice.

The other options are not consistent with standard vibration measurement practice. Measurements taken on thebaseplateorframeare generally made with contact sensors such as accelerometers or velocity pickups, not non-contacting probes. Option B is incorrect because vibration is not defined as being measured “on the shaft at 1.2 times the running speed” as a standard probe location criterion. The API guide includeselectric motors over 500 HPamong its covered equipment categories and emphasizessource inspection and quality surveillance activitiestied to applicable standards, testing, and verification during manufacture.

The correct answer isB. Theinterrupting ratingof electrical equipment is the maximumsymmetrical fault currentthat the device has been tested and certified tosafely interruptat its rated voltage and under specified conditions. In switchgear, circuit breakers, and related protective devices, this rating is critical because it confirms the equipment can open a faulted circuit without rupture, fire, excessive damage, or danger to personnel.

The term doesnotrefer to thepeakorcrestcurrent value. Peak or crest current is associated more closely withmomentary withstand,closing, orshort-circuit current peak effects, not the formal interrupting rating used for breaker application. It also does not mean ordinaryload current, because interrupting ratings are concerned with abnormal fault conditions rather than normal operating current.

From an API source inspection perspective, the inspector verifies that the nameplate data, test reports, and purchase specification all agree on the required interrupting capacity. If the interrupting rating is below the available fault current of the system, the equipment is unsuitable for safe service. Therefore, the correct definition is thesymmetrical current rating safely interruptible by the device.

The correct answer isC. In API 541, during thebearing temperature rise test, a motor bearing is considered to have reachedstable temperaturewhen thetemperature rise does not increase by more than 1°C over a period of one hour. This definition is important because the acceptance of the test depends on showing that the bearing temperature has effectively leveled off under the test conditions rather than still trending upward. If temperature continues to rise beyond that limit, the test has not yet reached thermal stability and the result cannot be treated as final.

This criterion is used in factory testing of large motors to confirm acceptable bearing thermal performance, lubrication condition, mechanical fit, and overall operating behavior at the test load and speed. In source inspection, the inspector verifies not only the final measured bearing temperatures, but also that thetest duration, stabilization criterion, instrumentation, and recorded resultscomply with the governing standard and approved procedures. A 30-minute interval is not the API 541 stability definition, and a 2°C rise in one hour is too permissive. Therefore, the correct API 541 requirement isa rise of not more than 1°C in one hour, which makesoption Cthe verified answer.

The correct answer isC. Arc flash PPE is required when a task exposes a worker to the possibility of anarc flash hazard, especially when testing or working onenergized conductors or circuit parts.Voltage testing in AC systemson energized equipment is a recognized task that can place the worker within the arc flash boundary, because probes, tools, or inadvertent contact can initiate an arcing fault. For this reason, proper arc-rated clothing and related PPE are required whenever the task assessment identifies arc flash exposure.

The other options describe tasks that are generally considered lower risk when performed under normal conditions. Work oncontrol circuits below 120 VACdoes not usually present the same arc flash risk level.Removing coverson properly installed wireways, junction boxes, and cable trays is not automatically an arc flash task unless it exposes energized parts and abnormal conditions exist.Insulated cable examination with no manipulation of the cableis also typically not treated as an arc flash exposure task.

From a source inspection and electrical safety perspective, the key principle is thatPPE selection is based on exposure to energized conductors and the likelihood of initiating an arc event, which makesCthe verified best answer.

The correct answer isA. UnderAPI 541, the vendor is required to provide thecalculated data from the final witness testing within two weeks following completion of the testing. This requirement recognizes that some final witnessed test results, especially those involving calculated performance values, are not always fully available at the exact moment the physical test ends. The vendor may need additional time to review recorded measurements, perform the required calculations, validate the data, and assemble the final certified test package.

This timing requirement is important in source inspection because the witnessed test may produce bothdirectly observed readingsandpost-test calculated results. The source inspector confirms that the testing itself was properly performed and witnessed, while the final calculated package must still be submitted within the standard’s required period so the purchaser can verify guaranteed motor performance and compliance. The other options are not the best match for the API 541 wording. “Upon request” is too indefinite, “at time of final shipment” may be too late, and “immediately upon completion of testing” does not allow for the calculation and certification process. Therefore,two weeks following testingis the verified API 541 answer.

The correct answer isD. In ANSI transformer standards under theC57.12 series, the impulse withstand capability assigned to transformer line terminals is expressed in terms of theBasic Lightning Impulse Insulation Level, commonly calledBIL. This value represents the crest value of a standard lightning impulse wave that the transformer insulation system must be able to withstand without failure. It is used to establish the insulation coordination of the transformer and to verify that external terminals and associated winding insulation can tolerate expected surge conditions on the system.

From a source inspection perspective, this requirement is important because the inspector must verify that the transformer design data, nameplate information, and test documentation match the specified insulation class and impulse withstand ratings. The BIL rating is a fundamental acceptance characteristic for transformers because it confirms the equipment’s ability to survive transient overvoltage events such as lightning surges.Switching impulseis a different category used more commonly on higher voltage equipment under certain system conditions.Chopped waveis a special test application, not the primary maximum insulation level designation asked here. Therefore, the correct maximum value is theBasic Lightning Impulse Insulation Level.

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.

The correct answer isA. According toNFPA 70, when aconductorpasses throughmetal, protection must be provided so that theconductor insulationis not damaged by sharp edges, burrs, or vibration at the metal opening. The concern is not the conduit itself, but theinsulated conductor surface, because abrasion at the point of entry can wear through the insulation and create a risk of short circuit, ground fault, arcing, or shock hazard. This is why bushings, grommets, insulated fittings, or other approved protective means are commonly required wherever insulated conductors pass through sheet metal, boxes, cabinets, gutters, or similar metallic openings.

The other options are incorrect becauserigid conduitandsemi-rigid conduitare wiring methods, not the protected element identified in this rule.Secondary circuitsare a circuit classification, not the physical component being protected from abrasion. In API-aligned source inspection and quality surveillance, this requirement is important when verifying panel wiring, junction boxes, control panels, and other electrical assemblies to ensure conductor routing and entry points comply with code and do not damage the insulation during service. Therefore, the correct answer isconductor insulation.

The correct answer isC. Source Inspector. In API source inspection practice, once a non-conformance report NCR has been issued and a disposition such as repair, rework, use-as-is, or reject has been approved, the responsibility forverifying that the approved disposition has actually been implemented on the productbelongs to theSource Inspector. This is consistent with the inspector’s core role in source inspection: to witness, verify, document, and report whether manufacturing and quality activities comply with the approved specifications, drawings, procedures, and disposition requirements.

TheVendor’s Quality Managermanages the supplier’s internal quality system and coordinates corrective actions, but is not the independent verifier for the purchaser’s inspection function. TheInspection Coordinatoradministers scheduling, communication, and inspection planning, yet does not normally perform the physical verification at the equipment level. TheManufacturing Engineermay define or support the technical correction, but implementation verification remains an inspection responsibility. Therefore, after NCR disposition is approved, theSource Inspectormust confirm through examination, records review, and where necessary witness of reinspection or retest that the disposition was properly carried out and closed.
