Current Carrying Capacity of a Cable

Current Carrying Capacity of a Cable Points : Current Carrying Capacity of a Cable The current carrying capacity of cable is limited by electrical and chemical deterioration of the insulation at high temperatures. One of the most common problems in cables calculations is that of determining the maximum permissible ampere for a cable. When a cable carries electric currents there is power losses occurred in the cable. Conductors and accessories (switches, socket) must be large enough to carry the maximum current without overheating. Conductors and accessories are rated in terms of current in ampere. Therefore, before the size of cable determined the consumption of the connected apparatus in amperes.
