I'm doing the work myself and having it inspected. I can easily calculate the volts drop myself and the cost effectiveness of different options, I just wondered if anyone had a gut feel for what the best option was.
My house was 24 metres from front to back. I have built an extension so it is now 33 metres. The circuit breakers are at the very front. I am adding new ring mains in the new extension, but calculated volts drop is a problem over that distance. What is the best way to wire this?
