Derating Factor For Cables In Cable Tray at Otto Atkinson blog

Derating Factor For Cables In Cable Tray. When using single conductors, single layer, with spacing in between conductors equal to the conductor diameter, in cable tray. Once you know your vertical stack line, you then look up the number of cables factor for that number of trays. Grouping the cables without adding space on cable trays is possible, but when calculating the maximum carrying current. Nec provides specific derating factors. De load factor is 1.0 for resistive loads and 1.1 for otherloads. This article explains why derating factors are needed, and the main factors affecting cable current ratings, and provides derating factor. Cable laid on cable trays exposed to air, the cables spaced by one cable diameter and trays are in tiers spaced by 300 mm. The cables must all be the same physical size (in terms. De actual conductor load is based on equipment full load ampere (fla) ratings. Do you use the derating factor for the three current carrying conductors and ambient temp or do you count all the conductors in each.
