Well, Emilio, I think that you may have just found the right place for this!. We had a whole host of posts here a wee while back on this very subject. Hey, and must say that you are the first to post from Brazil there mate, but we are all in the same boat here, just trying to learn more. I'll just go and have a look for you!.

It's quite intriguing the way that different color code standards developed over the years. Those of us who grew up in English-speaking countries always associate green with grounding conductors, and the thought anyone could have used anything else seems very strange (we've just about got used to green with yellow stripes now ).

Darren, Welcome to ECN, mate!. The answer to this question depends upon where you are installing the DC equipment. With Panel boards, this can mean anything apart from Red and Black, where the 240V wires use this coding. We have codings here of Violet, Orange or Grey.
