Assuming that there are no approved separations between conductors, which of the following conductors are permitted in the same cable or raceway as power-limited circuit conductors? Class 2.The maximum is trade size 4 for IMC and trade size 6 for RMC [Sec. 342.20, Sec. 344.20]. For complete systems, the number of conductors cannot exceed the percentage fill in Chapter 9, Table 1. Raceways must be large enough to permit the installation and removal of conductors without damaging the insulation [Sec. 342.22 …National Electrical Code (NEC) Table 310.104(C) is titled “Conductor Application and Insulation Rated 2,001V or Higher.” For MV solid dielectric cables, there are two basic types of insulation: thermoplastic and thermosetting. Thermoplastic is a heat-resistant plastic compound manufactured from polyvinyl chloride (PVC).the insulation condition from values that are only relative. The Megger insulation tester is a small, portable instrument that gives you a direct reading of insulation resistance in ohms or megohms. For good insulation, the resistance usually reads in the megohm range. The Megger insulation tester is essentially a high-range resistance meterWordly Wise 3000® Level 6, Lesson 6. 15 terms.
