The ampacity of a conductor is the maximum current it can carry continuously, under the conditions of use, without exceeding its temperature rating [Article 100 ...
The ampacity of a conductor can be determined either by using the tables in accordance with 310.15(b), or under engineering supervision as provided in 310.15(C). FPN No. 1: Ampacities provided by this ...
However, as the frequency increases; the current moves toward the outside of the conductor as indicated by the red and orange colors. This “crowding” is called the skin effect. Depth of penetration is ...
