My total incoming max is 60A. Incoming main wires will not change to CU, but inside the flat i am installing new wires. What minimum size, in mm, do i need from CU to water pipe and can i connect off this wire for supplementary use? Tnx.
In regards this Q and the previous i posted, the 30A switch; do i need to connect the earthing wire to the switch or can i directly run the earthing wire to the water heater and bypass the plastic switch box? Thnx 2X.
