What is the power rating of the equipment? P=IV so a 20A rating should not exceed theorectical 4.6kW max. and a 32A rating should not exceed theorectical 7.36 kW. This is assuming you only have one equipment connected. You need to make sure your source is at 230V and not 400V and that your source can handle the required power as well.
