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

The correct answer isA, power factor. In AC electrical systems, the phase relationship betweenvoltageandcurrentis an important indicator of how effectively electrical power is being used. Thecosine of the phase angle differencebetween voltage and current is called thepower factor. Mathematically, power factor expresses the ratio ofreal power, which performs useful work, toapparent power, which is the total power supplied to the circuit. When voltage and current are in phase, the cosine value is 1 and the power factor is unity. When they are out of phase due to inductive or capacitive effects, the power factor becomes less than 1.

From a source inspection and quality surveillance standpoint, understanding power factor is important when reviewing electrical test data, motor performance, transformer loading characteristics, and system efficiency information.Real poweris measured in watts,apparent powerin volt-amperes, andmhois a unit of conductance, so none of those terms define the cosine of the phase angle itself. Therefore, the correct technical term for this cosine relationship ispower factor.

The correct answer isD. API RP 14FZ. This document is specifically intended for thedesign and installation of electrical systems on fixed and floating offshore petroleum facilitieswhere equipment may be located inunclassified areas and hazardous classified areas identified as Class I, Zone 0, Zone 1, and Zone 2. The key clue in the question is the use of theZoneclassification system. In API and offshore electrical practice,API RP 14FZaddresses the offshore application of the zone-based hazardous area approach.

By contrast,API RP 14Fis associated with offshore electrical system guidance using the olderdivision-basedclassification approach rather than the zone terminology.NFPA 70is the National Electrical Code and is broader in scope; it is not the specific offshore petroleum recommended practice asked here.IEEE 841relates to severe-duty squirrel-cage induction motors and does not cover complete offshore electrical system design and installation requirements.

For source inspectors, recognizing the correct governing document is important because inspection and surveillance activities must verify compliance against the applicable design basis, hazardous-area classification method, and purchaser specification.

The correct answer isD. For aNEMA Size 2 motor controller, the appropriate conductor range is10 AWG to 4 AWG for 60°C rated cableand10 AWG to 6 AWG for 75°C rated cable. This matches the common NEMA controller terminal wire range used for Size 2 starters and controllers in industrial motor control applications. In practical source inspection and shop verification, this matters because the inspector must confirm that the controller terminals are suitable for the intended field wiring and that the manufacturer’s assembly, labels, and terminal data are consistent with the governing standard and purchase specification.

The API Guide for Source Inspection and Quality Surveillance of Electrical Equipment includesMotor Control Centersamong the major covered equipment categories for source inspection. The guide also makes clear that its focus is onsource inspection and quality surveillance activities, meaning verification of compliance with drawings, specifications, nameplates, and applicable referenced standards during manufacture and inspection. Since MCC buckets and NEMA motor controllers rely on proper terminal and conductor compatibility,option Dis the correct NEMA-aligned answer.
