Good luck with that...no disrespect intended. Are you a newbie to ACAD or just the Electrical version of it? Unless your company has already established a catalog of blocks and customized ACAD Electrical to suit their purposes you may as well use it a ACAD Vanilla and make your own stuff. OTB ACADE does not come ready to use for every electrical application there is. There are some things in it from the sample area, but unless it has been customized it's not much better that Vanilla with LISP and Block Libraries. IMHO
I work in the electrical field and may be able to help you with some symbols/blocks. Can you give more info on what you are doing and what you need? I'll try to help and there are tons of folks here that will be coming along soon. This is the best place for ACAD support - and great bunch of people.
