WebApr 11, 2016 · IPC-2221A has a single graph (currently figure 6-4), which the following equation for calculating the track current I I is derived from: I = kΔT bAc I = k Δ T b A c. where: k k = 0.048 for external traces, 0.024 for internal tracks. ΔT Δ T = the change in temperature (temperature rise) in ∘C ∘ C. WebIf there are more than three current- carrying conductors, the ampacity from the table must be adjusted based on the values found in NEC Table 310.15 (B) (3) (a). Adjustment factors range from 80% for 4 to 6 conductors, all the way to 35% for 41 or more conductors.
