Need to learn how to make wiring diagrams

[Cajun54]

I recently graduated with a bachelors in Mech Eng and have been asked to create some wiring and line diagrams for UL approved industrial control panels for my first job. I need some good resources to guide me through this... Any suggestions would be greatly appreciated.

Thanks!
