overheating may occur at the point of connection. Extreme heating can

installation, and periodic inspections of susceptible connection points

CODE TABLES BOOK
- You must understand the Code Tables to pass
an electrical examination
will be questioned over 425 times on the Tables
- Understanding the Code Tables is very important to the reader of the
book preparing to take an electrical exam. During my journey traveling
21 states, 84 cities preparing electricians for their license exam,
I've experienced the weakness the student had in applying the Code
Tables. Some have missed passing the exam by one or two points merely
by being unfamiliar with the Code Tables and how they are applied.
