|dc.description.abstract||Feeder circuit and branch circuit cable sizes are determined primarily on the basis of ampacity and voltage drop considerations. Rising costs of energy suggest a reassessment of currently used voltage drop criteria. Some degree of cable over sizing reduces cable resistance and cable operating temperature resulting in lower cable losses. A simplified method of analysis is presented which incorporates the effects of cable operating temperature. The analysis permits determination of cable loss savings for various choices of cable sizes. The method is extended to include cost of cable and expected future costs of energy so that an economical choice of cable size may be determined. An example is presented to illustrate the method. It is shown that a relatively simple modification of currently used ampacity tables permits determination of cable sizes taking into account today's energy economics.||en|
