I wonder if anyone has done a study to see if there is any correlation between electricians scores on their qualification exams and their life expectancy?
At least for the Maryland Master Electrician test, there's a time limit with too many questions to spend enough time on each one. For example, the final 6 questions count 5 points each, but each one is a test in itself where you have to determine the size of the feeder transformer powering different building, such as an apartment complex, college dorm, commercial store front, etc. So I can spend maybe 10 minutes on each question max, and you have to show your work. If I was in the business of installing electrical power for apartment buildings (which I have never done, or plan to do) then I would spend a lot more than 10 minutes determining the size of the transformer based on the number of units in the building, number electric ovens, number of electric clothes dryers, air conditioning units, etc... If fact I would probably build an Excel spreadsheet with all the proper formulas and de-rating percentages, then plug in the number of apartment units and appliances to get the final KVA value. It might take me a few hours to build the spreadsheet once and test it, but after that it would be 5 or 10 minutes of plug & chug for each calculation. Plus I find a lot of information via a search on the pdf, which is really quick (and perhaps a little lazy on my part). But the written test requires you to use a physical copy of the book and mark it up with little tabs. That does help a lot, but realistically that not how I work nowadays.
