I recently acquired a confidence pro vibration plate machine but it came without the power plug! What cable would i need for this? It's got a label where this plugs in which says 230v 50hz 600w & i can see it has three pins and a triangular sort of socket for the power supply to fit in. (Like a pc cable or kettle cable) but I'm not sure if any sort of pc cable/kettle cable will do or does it need to be able to withstand the power units above?
