NEC Code Test - Table Tip 1

Take time to familiarize yourself with these tables. It doesn't matter if you are taking the journeyman or master exam. You’ll need to know these tables either way. The only difference is what you will have to do with these tables in the exam. The master exam will have more complex questions in regards to these tables.


Understand what these tables do. Learn how to work them. Also know how they apply to the articles and test questions.

NEC Code Test - Table Tip 2

Always use a ruler or straightedge. If you're using the table values, especially the ones that have such a dense amount of material, you'll need one.  You also need them for the tables that are spread all across the page. For example, the tables back in Chapter 9 or Chapter 4.


There's nothing worse in the world than to know exactly how to answer a question yet get it wrong. Even if you know what table it is you're supposed to reference. Why does this happen? Maybe because you just let your fingers slip down accidentally or your eyes are tired.


Use a straight edge!



You'll get a piece of scratch paper when you walk into the exam room with your name. You can just double that over and use it if they have nothing else to use as a straightedge.
