Electrical Symbol legend
Electrical Symbol legend
(OP)
Can anyone direct me to a source where all electrical symbols are displayed and identified. This would be a benefit for understanding the difference between the european symbol standards (eplan) and the North American standard (promis.e)

See also the enclose Thread242-22239
Be advised that Tennessee Valley Authority (TVA) among other government or private utilities have their own symbols before this standard was originally published.
NOTE: I understand that there is a publication with the equivalent symbols between the IEEE/ANSI and IEC.
If you should find any good reference, please let us know.
