The discussions about Master Electricians bring up an interesting topic. PA has no statewide licensing, but the City of Phila. has an "Electrical Contractors License Exam" it is 4 hours, open book with approx. 40 questions with answers found directly in the NEC, about 20 found by using the NEC tables, calculations, etc. and about 20 theory & diagrams.(At least from what I remember in 1990). 70% to pass. Most of the suburban areas only have a form to fill out, and voila, instant Electrical Contractor. I know NJ has a 7 hour test with all of the above, plus business law & fire code. Delaware has a Master Electrician. There are also Apprenticeship/Journeyman programs available locally through the unions or also for open-shop organizations. What do some of the other areas of the country require?
