How do you calculate armoured cable cross-sectional area?
For electrical purposes the formula for calculating the circular-mil area of a circular wire is very simple. A = D squared, Area equals diameter of the cable or wire squared. This calculation is needed when pulling cables into a cable tray so as not to overfill the tray. Over filling a cable tray will build up a heat from the cables if proper ventilation between the cables is not maintained.
