I have Mike's Electrical NEC Exam Preparation book and I have a couple of questions. On page 485, question 22. How do you know that the two multioutlet assemblies are different? The way I read the question, you have a 50' and 10' assembly that are both simultaneously used. The next question is on page 486, question 32. The question is asking about 17 "dedicated" 20A tent sites, but in the answer book they use the 2400VA rating, not the 600VA for dedicated. Why is that? One last question...I've taken the Wisconsin Masters twice now. Both times I felt like I was well prepared. Both times I missed. Any ideas on how better to prepare? Thanks for your time.
