Note: View additional wire size charts from the list below. Wire Size Chart and Maximum Amp Ratings Source: NFPA 70, National Electrical Code, Table 310.15(B)(16) SIZE The wire size chart below shows allowable ampacities of insulated conductors rated up to and includingĢ000 Volts, 60☌ through 90☌ (140☏ through 194☏), not more than three current-carryingĬonductors in raceway, cable, or earth (directly buried), based on ambient air temperature of 30☌ (86☏). The number of devices connected to the circuit usually determines how much current will flow through the wire. It is important to pick the correct size of wire so that the wire doesn't overheat. Limit that a wire can handle before damage occurs. Multisim comes with standard sheet sizes that you can use to capture your. Compared to the bigger 10 AWH wire with a 5.26 mm2 cross-section, the 12 AWG wire is 59 smaller. Let’s compare the cross-section of 12 vs 14 AWG wires and 12 vs 10 AWG wires: Compared to the smaller 14 AWG wire with a 2.08 mm2 cross-section, the 12 AWG wire is 37 bigger than the 14 AWG wire in area. Each wire size, or wire gauge (AWG), has a maximum current A 12 gauge wire has an area of 6.53 kcmil.
