you could have fixed it the builders method. connect the neutral wire to the earth terminal. that would work temporarily. you'd have to bypass the RCD with a couple of bits of 1.0mm though. (and in case anybody thought i was serious, my your god help you)
I'd have to question you using 1.0mm cable mate, surely the CSA of it will be too big to trip the 100A RCD? I'd use bellwire myself. But then I know what I'm talking about because I completed my 5 week course. Its people like you who give us cowboys a bad name.
