Hi

i'm experienced in Electronics Schematics and PCB Design.

First time i need to work on electrical CAD Drawings. I've a task of migrating electrical drawings which are in NEC standard into IEC Standard. This is specific to Photovoltaic power generation domain. Can someone guide me specifically for symbols, measuring system and the equivalent IEC Standards or give me any document which gives important points to execute this task.

thanks in advance

 

There is no such thing as NEC standard drawings.
