For DC
Above are from the Blue Book
What's ELV? There's not a single mention of it in that pdf.
Edit: nevermind, I found it on wikipedia. Extra-low
Sorry ELV is in a blue book supplement not in the main book. Extra low voltage work in Australia doesn't need a license, just have to be competent.
Not the one I was thinking of but it does define Extra low voltage
Neat, I didn't realize they were defined like this but that totally makes sense for regulations and such. Thanks!
