9 9. rigid Metal Conduits Technical Cable Capacities of Conduit The following tables give guidance of the calculation of the number of single-core insulated cables which can be located in various sizes of Conduit . The tables deal with two particular cases: (i) Single-core insulated cables in straight runs not exceeding 3 meters in length (ii) Single-core insulated cables in straight runs exceeding 3 meters in length or in runs of any length with bends or sets STRAIGHT RUNS NOT EXCEEDING Sum all the cable factors and compare with the Conduit 3 METERS IN LENGTH factor given in Table 4 for the relevant length of run and the number of bends and sets in that run. For each type of cable being used obtain the cable factor from Table 1, Sum all the the cable factors and compare The Conduit sizes which will accommodate the cables are with the Conduit factors given in Table 2. those with a Conduit factor equal or greater than the sum of the cable factors. The Conduit sizes which will accommodate the cables are those with a Conduit factor equal to or greater thean the sum of the cable factors.
