can you please advice me on how many Amps i would need to power off the following (using 3 Phase Board):

Commando with:
60A RCCB

50Hz
4 Pole

From this to a Machine (Wap Reiningungssy Steme) that have the following:
380V

This machine is used at a carwash for pump hot water to wash cars. "I'm not sure about the cable size"

your way over the limits of your cable there, speak to an electrician about a new cable!
