I passed the MN Master exam this past week. I used the exam prep books, and prepared for about 3 months. For anyone that is looking to take the MN Master exam soon, I would study a lot of motor and transformer theory, short circuit ratings, and service calcs. It was a lot of calculations. If anyone wants more info on the types of questions, just let me know.

Good job.

How was the MN master exam? I took it back in 2004 before they changed to a new format. I was told the new exam is harder then the older version?

I guess I am not sure how hard the old one was. I know when they first came out with the new exam pretty much nobody passed. They then modified it some and got it up to where a certain percent were consistently passing it.

MN Exam

I am taking the exam this August in St. Paul. I would love to get any info that I can. Here was a question that I posted.

2-story office building, 80x125 feet, supplied by 120/208V, including minimum demand for receptacles and continuous light, what minimum feeder is required? I calculated 20k ft^2, so at 1VA/ft^2 for receptacle, apply the demand factor (100% up to 10kva, 50% after), and 3.5 VA / ft^2 for lighting plus 1.25% for continuous. I could not get an answer that was in the answer selection. I did include sqrt3, I tried excluding it, I tried continuous and non continuous for the light and receptacle load, NONE of these combinations gave an answer even close to one of the answers.
