  1. Yes, but only a difference of seven problems. The newest edition of the NCEES® practice exam was released in November of 2017. Want to know if: The new one is worth the money? What subjects the new seven questions are on? What subject the old seven questions were on that got replaced? Plus a few interesting findings that helps give some insight into the PE exam We wrote up an article that answers all the above questions when the new practice exam first came out:
  2. Hi @Valox, @M's and @ej_powereng the electrical power PE practice exam is available now: Electrical PE Review - Practice Exam
  3. Hi @Wow! The NEC® is pretty clear on when to use the name plate amps, and when to use the 430.250 table values. NEC® 430.6(A)(1) instructs the use of table values instead of "the actual current rating marked on the motor nameplate" for the ampacity of conductors, ratings of switches (any device that makes or breaks a circuit), branch circuit short circuit and ground fault protection. This applies to all motors except those "built for low speeds, high torque, or multi speed motors". NEC® 430.6(A)(2) instructs the use of "motor nameplate current rating" for separate overload protection. PM me your email address if you'd like a copy of our four page PDF motor cheat sheet that we give out to our students after our live class on rotating machines:
  4. Hi @leo2car, we are releasing the first edition of our sample exam in the next couple of weeks. Would you like a free copy? I am thinking of giving it away for free for a limited time on engineer boards.
  5. I get a lot of emails regularly asking for help with the 4 wire "high leg" delta transformer. Here is a quick video explaining how to calculate the high leg voltage that you may find useful: If you'd like to download a copy of the completed circuit diagram, the completed phasor diagram, and all of the steps in this video to use as a cheat sheet for your exam references then visit the full length article here: Electrical PE Review - 4 Wire High Leg Delta Transformer Connection I hope you enjoy the short how to video and cheat sheet. I'm happy to answer any questions that you may have.
  6. Sure thing. If you have any questions @Toby-Wan feel free to reach out directly via Email.
  7. Glad to have you @MadamPirate, don't forget you can always email in any questions that you have in addition to asking them during each live class.
  8. Looks like a good book! I just picked up a copy on amazon to review it.
  9. Hey @LyceeFruit, don't worry. What you are feeling is completely normal. The amount of material to cover can be a little intimidating at first, there is A LOT to learn. I promise that by the time the exam comes around, you'll be feeling much more comfortable. Before you know it a lot of subjects are going to start clicking for you, especially after we cover each of them in live class starting next week. Don't forget you can always email me when you need help! Hope to see you in the live chat room next week for the first intro class, I'll be looking for you! Edit: I forgot to mention, since you asked, my favorite subject is circuit analysis. Especially the problems that seem very complicated at first but can actually be reduced to different fundamentals that piece the problem together. The really nitty gritty of it that lends itself well to many other areas of the exam.
  10. Glad you've enjoyed our youtube videos. I suggest signing up for the Free Trial of our online review course for the electrical PE exam if you haven't already. There is a large amount of material in it that you won't find on our YouTube channel, including a large number of practice problems with worked out solutions and plenty of reference material you can print out and take with you to the exam.
  11. I agree, Blackburn's book is a bit overkill. It's a great book on protection, just not very applicable for answering questions on the PE exam. We've been recommending Power System Analysis by Duncan Glover instead, which is currently #5 on our list of recommended references for the electrical PE exam. There is only one chapter on protection, but it is filled with in chapter examples that are worked out with solutions that appear to be consistent with the PE exam. The end of chapter questions on protection are also great if you can get your hands on the solution manual. The majority of the other chapters in the book area also subjects that appear on the PE exam. It is one of my most recommended books.
  12. Always happy to hear when people are enjoying our review material.
  13. Is it possible that the asterisk is meant to just be multiplication and the load is purely resistive (I.e. no need to multiply by power factor)? Or is it possible that the book accidentally put the conjugate in front of the I by mistake? It would be helpful to see the full problem and solution.
  14. Hi @Eng-Moe, review courses are talked about a lot on the forums, especially in the results threads after each PE exam. The search function would be a great way to find what others have already discussed. Here are a few threads I found by typing in "review course" and "pass" into the search bar:
