CHAPTER METHODS AND MATERIALS - Mike Holt
mike holt Enterprises, Inc. ( )99 CHAPTER3 wiring METHODS AND MATERIALSINTRODUCTION TO CHAPTER 3 wiring METHODS AND MATERIALSC hapter 2 provided the general rules for wiring and protection of conductors, and was primarily concerned with the correct sizing of circuits and the means of protecting them. This differs from the purpose of CHAPTER 3, which is to correctly install the conductors that make up those 2 was a bit of an uphill climb, because many rules had a kind of abstract quality to them. CHAPTER 3, on the other hand, gets very specifi c about conductors, cables, boxes, raceways, and fi ttings.
• Control, signal, and communications wiring must be sepa-rated from power and lighting circuits so the higher-voltage conductors don’t accidentally energize the control, signal, or communications wiring: – CATV Coaxial Cable, 820.133(A) – Class 1, Class 2, and Class 3 Control Circuits, 725.48 and 725.136(A).
