    Hello! According to the PUE, for one three-core cable with aluminum conductors laid in the pipe, the maximum permissible current is 38A. But with an increase in the line length, the permissible current decreases due to an increase in its resistance. In short, if you use the machine on 32A - most likely there will be no problems.
