prudent to consider busbars.
Notes for IEC 60364:
1. IEC 60364-5-52 table A 52-12 F method column 5 = Single core cable in free air.
NOTE
2. IEC 60364-5-52 table A52-14 correction factor for ambient air temperature others
than 30°C.
3. IEC 60364-5-52 table A52-17 item 4 correction factor for groups of more than one
circuit or more than one multi-core cable placed on a single layer on a perforated
tray.
Notes for US National Electrical Code:
1. Table 310.17 allowable ampacities of single-insulated conducted rated 0 through
NOTE
2000V in free air, based on ambient air temperature of 30 °C (87 °F).
2. Derating factor of 0.88 is applied for 40 °C to the 75 °C cable column. Table 310.17
is based on 30 °C (86 °F) ambient air temperature.
3. NEC 2005 edition table 310.15(B)(2)(a) shows the adjustment factors for more
than three current-carrying conductors in a race way or cable, for 4-6 current-
carrying conductors 0.80 derating factor is applied.
