    Which electrical symbols library should I use?

    When you install AutoCAD Electrical you have multiple libraries. Relating specifically to IEC standards there are IEC2, IEC4 and IEC60617 symbol sets.

    IEC2, IEC4 and IEC60617 are all in accordance with the IEC60617 electrical specification. However the IEC2 and IEC4 libraries will number the components when placed in accordance with IEC61346 whereas the library IEC60617 will number the components when placed in accordance with IEC81346.

    IEC4 basically has the same size symbols graphically as the IEC2 library but the text is larger.

    What do other customers use? Most companies use IEC2 and IEC2/1-
