3*6 aluminum wire can withstand 15kW motor. Single-phase equipment with 3*6 square copper wire has an hourly current carrying capacity of 36A and a power of 7.2kw with three-phase load, and the power of 3 * 6 square copper wire is 18kw. The square line of 3*6 becomes an aluminum line. The rated current of 3x6 aluminum wire is 3oA, and the corresponding power is 6kw. 3*6 square aluminum wire with three-phase load, 3*6 square aluminum wire with 15kw three-phase equipment. According to the above, the load of copper wire or aluminum wire is different with the same wire diameter.
