質問 # 53
What standard is used for the installation of signaling and communications conductors, equipment, and raceways?
正解：D
解説：
The correct answer isC, NFPA 70. NFPA 70 is theNational Electrical Codeand it is the primary installation standard used for electrical wiring systems, includingsignaling and communications conductors, associated equipment, and raceways. In source inspection and quality surveillance, the inspector must verify that electrical equipment and its installation-related features are consistent with the applicable code requirements identified in the purchase documents and project specifications. For signaling and communications circuits, NFPA 70 provides the governing installation rules for conductor methods, separation, protection, routing, and raceway usage.
The other options do not fit this question.NEMA 250covers enclosure types and environmental protection ratings for electrical equipment enclosures, not installation rules for communications and signaling systems.
IEEE C37.20.2applies to metal-clad switchgear, so it is equipment-specific and not the general installation code for communications conductors.IEC 20047is not the recognized answer in this context.
From an API source inspection perspective, this distinction matters because inspectors must know whether they are checkingequipment construction standardsorfield installation code requirements. For signaling and communications installations, the correct governing standard isNFPA 70.

According to NFPA 70, the number of bends permitted between pull points for rigid metal conduits RMC shall not be more than:
正解：A
解説：
The correct answer isB. NFPA 70, which governs installation requirements for electrical raceway systems, limits conduit runs between pull points such as outlet boxes, junction boxes, conduit bodies, or pull boxes tono more than the equivalent of four quarter bends, or 360 degrees total. This rule applies to rigid metal conduit and is intended to ensure that conductors can be installed, pulled, and replaced without excessive mechanical stress or insulation damage.
From a source inspection and quality surveillance perspective, this requirement is important because conduit routing directly affects installation quality, conductor integrity, and maintainability. Excessive bends increase pulling tension and sidewall pressure, making conductor damage more likely during installation. Too many bends can also complicate future maintenance and cable replacement. During inspection of electrical systems, the source inspector verifies that conduit design, fabrication details, and installation-related drawings align with code requirements and do not introduce nonconforming field conditions.
Option A exceeds the code limit. Options C and D introduce bend-radius conditions that do not replace the fundamental NFPA 70 maximum of360 degrees between pull points. Therefore,Bis the verified answer.

According to the referenced API standard in the guide, special purpose induction motors covered by API STD
541 are:
正解：B
質問 # 56
According to API 541, for the bearing temperature rise test, motor bearing stable temperature is defined:
正解：C
解説：
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.
