Once there, click on the free access link to theВ latest edition of NFPA 731.Д¤.6.3.12 At raceway connections to junction boxes and open ends of raceways, the following shall apply: For the complete section, see the actual NFPA 731 text at NFPA.ORG. Refer to the image of NEC Annex C Table C.1 to answer the question below.Д«elow is a sample of NFPA 731. For example, Table C.1 in Annex C provides the maximum number of conductors or fixture wires permitted in electrical metallic tubing (EMT) while Table C.3 provides the maximum number of conductors or fixture wires permitted in flexible metal conduit (FMC). There are a few different types of manufactured pull points and they are typically made of a similar. Generally called pull boxes these devices create intermediate spots in conduit runs where you can pull the wire from. There are many tables in NECВ Annex C, each of which is for a different raceway type. A conduit pull point is essentially any device with a removable cover that allows access to the wires inside the conduit. NEC Chapter 9 is used for combinations of conductors of different sizes or insulation types installed in the same conduit or tubing.NEC Annex C is used for determining the maximum number of conductors permitted in conduit or tubing, when all conductors in the conduit are of the same size and insulation type.In the NEC, there are two main locations (near the back of the book) used when determining the maximum number of conductors in a conduit or tubing: Raceways, conduits and tubing are not always used with security system wiring but if they are, the raceway conduit or tubing must be sized according to the NEC. Modifying existing electrical circuits or installing additional electrical wiring should be done according to local and National Electrical Codes, with a permit and be inspected.NFPA 731 Section 4.6.3.12(2) requires raceways to be sized properly in accordance with the NEC.
