Oregon General Supervising Electricians Exam

I took it 7 years ago.

At the time, the way to do it was to take one of John Powell's supervisor prep courses and then take the test as soon as you could after taking his classes.

He wrote all the different versions of all the electrical tests the state uses, so you were being taught in his classes the same way you'd take the test. I'm not sure if that's a conflict of interest or not.

I was told a couple years after I took the test, they made it easier as the passing rate was still too low.

But, this topic still comes up every once in a while on here, so it must still be tougher than other states, because I don't see other states brought up on here. Just being a member on this forum tells me you have a better than average shot at it.

When I took it, it was obscure code articles for the main code questions, and an industrial warehouse with equipment and office space for the long drawn out calculation. If you were wrong on one of the calcs, all the other calcs that piggybacked off of it were wrong as well and you failed the test.

You need to fully understand art. 220.

Thanks COW, I appreciate it. I’m taking tutorial classes from Deb Marinos that have been very helpful. I was looking for someone that had taken it in the last year or so for the latest insight.

I took it about 6 months ago. I took it three times :ashamed1: failed the 12 question calculation part by one both times. The Code part was easy since its open book. Every test had 7-8 questions that were tied together. Had some PV questions.

If I did not pass the third time I was going to take John Powell's
courses. Like Cow Said 220 is a must to understand.

I filled my code book on the back blank pages with every formula and some question similar to the ones I remembered while taking the other ones. Studying annex D very heavly helped also, just looked back there on my highlited notes when stumped.

You should be good though, Your smarter than me lol.

I suggest that it was only easy because you were already -very- familiar with the code, and only needed the book for the details! Unless you know where in the book to look, it's going to be a difficult exam!

Well prior to studying Mikes complete library I took a 2 year absents from electrical work(cold turkey). So I studied his material for 6 months. Without that I would of failed it.

for the Code part, you need Tom Henry key finders. I used that for about 50% of the questions

I Also went threw my uglies, sat down and did every example question in their book.

Thanks for the tips! I’ve started the notes in the back of the code book. My instructor suggested the Henry’s key word index, which is very helpful. The tools are all there, but the consensus seems to be practice, practice, practice. I’m trying to do at least 1 practice calculation per day.
