I am looking for ANSI and IEC standard ELCB,RCCB,RCD electrical schematic symbol. Can any one help me on this ?

Here are a few websites to get you going in your search.

IEC 60617 - Graphical Symbols for Diagrams (http://std.iec.ch/iec60617)

http://electrical-designer.com/

Download Electrical IEC 617 Symbols 6.5- Version 6. 05. 0 and a grid setting of 8 - download.cadinfo.net (http://download.cadinfo.net/CAD-Manager/General/Symbols/Electrical-IEC-617-Symbols.html)

You will need to subscribe to ANSI, IEEE, and IEC to obtain exactly what they offer.

Is there a specific symbol you are looking for or are you looking for a generalized set of electrical symbols?

I am looking also

Hengsens,

Nice to meet you to. Do you always start by disagreeing with a question? Because all I did was ask the poser for more information on what he was looking for. Not to mention that the original post is just about a year old!

Now if you wouldn't mind, tell me what you are looking for and I may choose to help.
