Good beginner's book for power designers?

I work for a small engineering firm that designs HVAC, plumbing, fire protection, and electrical systems for commercial and residential buildings. Presently, I am an electrical draftsman. The company hopes to gradually give me more and more design work. I'm looking for a book that will give me a good foundation in electrical design. It'd be helpful if the book included information on lighting design, as well. Or if there is a separate book you could recommend on lighting design, what is it?

Thanks. I greatly appreciate any advice you guys can give me.

p.s. If you look at my profile, check out my post history. My last post asked the HVAC people for a beginner's HVAC design book. My company keeps moving me around. Haha.
