API-SIEE Exam Questions

The correct answer isC. One-line drawing. In switchgear inspection and acceptance testing practice, fuse ratings and circuit breaker sizes and types are verified against theapproved one-line drawing, because that document defines the electrical distribution arrangement, protective device coordination, feeder identification, equipment ratings, and the intended relationship between upstream and downstream protection. During source inspection and quality surveillance, the inspector must confirm that the installed protective devices match the project design documents and purchase requirements. The one-line drawing is the key reference used to verify whether the correct breaker frame, trip rating, fuse class, and protective arrangement have been provided.

The other options do not serve as the primary verification basis for protective device size and type. Atransformer nameplategives transformer data only, not the full protective scheme for the switchgear lineup.Shutter installation operationrelates to safety and mechanical function, not device sizing. Acurrent transformer turns ratiois associated with metering and protection circuits, but it does not determine the required fuse or breaker type for the overall lineup. Therefore, the proper reference for verifying fuse and circuit breaker sizes and types is theone-line drawing.

The correct answer isB. The inspection coordinator. In the API source inspection framework, the inspector's role is to independently observe, verify, document, and communicate quality-related concerns through the established inspection reporting chain. When schedule pressure appears likely to compromise product quality, the issue must be escalated to theinspection coordinator, because that person manages inspection execution, communication flow, and coordination between the purchaser, supplier, and inspection function. This keeps the inspector independent and ensures the concern is addressed formally rather than informally.

The other options are less appropriate. TheMaster Scheduleris responsible for planning and timing, not for controlling inspection escalation. Theshop QA Managerbelongs to the supplier's organization, so reporting directly there could weaken the inspector's independent reporting path. TheProject Managermay ultimately need awareness, but the normal and correct first notification route in source inspection administration is through the inspection coordinator. This approach aligns with API source inspection practice, where quality threats, deviations, and risks are communicated through designated inspection channels so that corrective action, hold points, and surveillance priorities can be managed properly.

The correct answer isCbecauseapparent powerin an AC electrical system is measured involt-amperes VA. Apparent power represents the total electrical power supplied to a circuit and is the combination ofreal powerandreactive power. Real power, which performs useful work such as turning a motor shaft or producing heat, is measured inwatts. Reactive power, which supports magnetic and electric fields in inductive or capacitive equipment, is measured invars. Apparent power is therefore the vector sum of these two and is expressed inVAor larger units such askVAandMVA.

The other options are incorrect for this reason.Mhosis a unit of conductance, not power.Varsmeasure reactive power only.Wattsmeasure true or active power only. In source inspection and quality surveillance of electrical equipment, understanding these distinctions is important when reviewing motor data sheets, transformer ratings, switchgear load data, and electrical test reports. Equipment such as transformers and generators are commonly rated inkVA or MVAbecause their thermal and current-carrying capability is tied toapparent power, makingvolt-amperesthe correct answer.

The correct answer isAbecause the group of performance items listed in the question---efficiency, power, locked-rotor current, power factor, torque, full-load current, and slip---belongs to acomplete testfor large electric motors under API 541 practice. A complete test is broader than a routine production test because it verifies the motor's full performance characteristics, not just basic manufacturing acceptability. These measurements are used to confirm that the motor meets its guaranteed operating and starting characteristics and that its electrical and mechanical performance aligns with the design and specification requirements.

Aroutine testis normally more limited and is intended to confirm standard production quality on each motor, such as winding resistance, insulation checks, no-load current, vibration, or similar baseline acceptance items. Adesign testis generally associated with proving a design type rather than verifying all ordered motor performance data on a specific unit. Acompliance testis not the best match for this defined set of performance determinations. In API-aligned source inspection, these performance verifications are associated with thecomplete test, makingoption Athe correct answer.
