So now they need to write new standards all the time to make money. When I was much younger there were not many electricians who understood low voltage DC at all. I saw plenty of off grid houses wired just the same as a grid house would have been wired. The outcome was ( before LED lighting) that one light was switched on all good, two lights on they both dimmed a bit, more than two lights on the dark ages came fast. They did not take voltage drop or cable sizes into account. Now with lots of solar panel installs, more sparkies are working with DC. But mostly medium voltage levels. Still low voltage is a mystery to some. Here is a link to an article that goes into just how difficult the standards are to interpret. MC sparky on Au standards Pete
