In the ring system how are the conductors sized? If it is protected at 32 amps at the service panel are the conductors able to handle 32 amps if the ring should become broken? If so, then it seems to me that copper is saved due to wire size only because of the higher voltage. In the US wires are fused at 15, 20, and 30 amps for #14, #12, and #10 wire respectively.
