Hurk's right. I just helped put together the Ramsey Test for Maint. Elec and Mech. about a year ago.
We had people from all of our locations (maint Mgrs, EEs, etc) around a table. The potential test questions were given to us. We did a round robin answering the questions and then each rated that question on its improtance to the craft. Took a full day. Talk about being put on the spot when it came your turn. I had one guy ask me how I knew the answer to a particular question. All I could say was, I guessed. You had to be there, but it got a laugh.
Why is it, when it comes to the NEC, the obvious is never simple and the simple is never obvious?
