Answer Posted / Pundreekaksha Sharma
The size of a 3-phase 4-wire cable for a 11-ton ductable A/C can be determined based on the current rating and voltage level required. The calculation involves considering factors like the total power (in watts) of the AC unit, the operating voltage (typically 208V or 460V), and the allowable current density for the cable insulation material. It is recommended to consult with a qualified electrician or refer to National Electrical Code (NEC) standards for accurate cable sizing.
