DIY Electrical work book recommendations?

["Mark Andy" <mark@sccaprepared.com>]

Howdy,

A friend is interested in wiring his own (detached) garage including the
subpanel & feed from the main house panel and asked me if I had any
recommendations for good books to learn to do it properly & to normal
code, etc.  He's not an idiot and is mechanically adept, but he's not done
much house wiring before.

Anyone have any good book recommendations?

Thanks!

Mark
