I purchased an Ecosmart 8 Instantaneous hot water system from Amazon and its really made for the North American market. The wiring says it need two active wires to make up 240 volt and no Neutral, Customer support have also told us this, however in Australia we have one red active wire and a black neutral wire. And of course yellow/green earth. Its wired up ready to go with red and black making up 240 volt. Will this work or am I going to damage something? If not how are we expected to wire this up? Thanks in advance.
