I am scheduling my journeymans test for my EL06 here in Washington State. I have my NEC 2005 and my WAC and RCW. I have a couple questions. 1) What kind of math do the low voltage test include 2)Are there any other books I can use for this test? I have an exam content outline. Seems pretty straight forward, but do they tell you in what article a question is going to pop up in?
