Step 4: Determine the cross-sectional area of the conductors to be added [Table 5 of Chapter 9 for insulated conductors and Table 8 of Chapter 9 for bare conductors]. Step 5: Divide the spare space area (Step 3) by the cross-sectional area of the conductors to be added (Step 4). Now you should be ready to tackle a sample calculation. Q.See Answer. Question: The NEC Chapter 9, Table 8, gives 1.93 ohms for the same piece of wire. The difference in resistance is due to a temperature difference. Use the following formula (from the NEC, Table 8-Notes) to determine the resistance of 1,000 feet of #12 wire at 105°C. Calculate to two decimal places.Informational Note: Table 352.44 and Table 355.44 provide the expansion information for polyvinyl chloride (PVC) and for reinforced thermosetting resin conduit (RTRC), respectively. A nominal number for steel conduit can be determined by multiplying the expansion length in Table 352.44 by 0.20. The coefficient of expansion for steel electrical metallic tubing, ……
