A Written Guide

This digital download contains Chapter 4 from my book "A Comprehensive Guide to Passing the Electrical Licensing Exam". It is a written guide to understanding math that you should know before the exam. It includes electrical topics such as box fill, junction box sizing, pipe fill, conductor correction and adjustment factors, and voltage drop. These topics can be found in the NEC but are often hard to understand. This information is considered to be at the journeyman level. 

It's so easy, after working years in the field, to forget about these formulas by the time your licensing exam comes up. Every question counts! Don't struggle to pass because of problems like this. Refresh yourself with this written guide!
