NEC
National Electric Code. A book containing all the rules regarding electrical work. It is currently available at amazon.com for about $65. Your local library should have a copy. The rules are updated every three years, so you need to know which version your city has adopted. The NEC is published by the National Fire Prevention Association, and it’s safe to assume that the purpose of the NEC is to prevent electrical fires due to unsafe installations. Some cities make amendments to the NEC guidelines. For example, my city, Austin, Texas, has adopted the 2005 NEC with some local changes.
