Analyzing the temperature increase inside the electrical cable as the alternating current flows inside the cable.

Hi, I am modelling a single phase electrical cable with insulation layers. The cable consists of live , nuetral and earth wire. I want to make the AC current flow in the cable and analyze the temperature increase in the insulation layers of electrical cable. I am using Magnetic Fields>Coil>coil current, but I am not able to generate the alternating current in live and neutral wire. Kindly tell me how to generate the AC current in the live and nuetral wire. Your help is very much appriciated. Thank you.
