To All, i would love to know that too. In Britain a single house supply is only rated at 20 kW (80A -at-240v). So I can only presume if you want to run above that you will need to put in an industrial supply (costs $$$). An you can't just run above that and hope the cable can take it as there is a master fuse, 80A, which is sealed by the electricity company that would blow. NicK Field
