I have not yet taken the actual PE Power exam, so I can't fully answer your question. But I will try to rank the difficulties of the various practice exams that I took... In my opinion, from hardest (1) to easiest. 1. Cram for Exam Volumes 1 thru 4 (80 questions each volume) - various...

IMO, The best way to deal with autotransformer questions is to visualize the windings directly in series, and seeing which common winding and series winding combination will lead to the desired primary and secondary voltages. The autotransformer rating will always be: S auto = V in, auto * I...

Zach Stone's Electrical PE Review practice exam questions, Engineering Pro Guides practice exams, and Cram for Exam practice exams. One very good kind of relevant example off the top of my head is from Engineering Pro Guides. It's a conceptual question. Basically the question gives you a...

Here are a few diagrams/illustrations I previously drew up for a similar topic in this board to show over-excited synchronous machines relationships. Whenever a synchronous machine (synch gen or synch motor) is over-excited, it always delivers reactive power Q. Re(Ea) > |Vt|: over-excited...

Congrats

Congrats!

I do believe that you should bring a printed copy of the email from Pearson when you first scheduled your exam date, correct?

I also have a COVID-related question to ask. I know that you obviously have to wear a mask for the duration of the exam, and you can't show up to the exam if you're positive (stay safe and healthy, everyone!)... Are there any other COVID or health-related requirements for the CBT exam that we...

You're talking about NEC Table 240.6(A), right? My interpretation/understanding is this: Table 240.6(A) is for STANDARD sizes. There can also exist circuit breakers and fuses with non-standard sizes. These days I believe there are electronic-style breakers, fuses, and OCPDS whose trip setting...

In all fairness, the question doesn't ask for a maximum standard size, only an allowed maximum. It's rare, but I have seen a few questions that have asked only for a maximum or minimum, not necessarily a standard size. One example I remember is from Zach Stone's Electrical PE Review exam. He...

Ok, thanks! I'm just trying to cover my pre-exam bases. This occurred to me while reading the examinee guide a few days ago. Also one other thing I saw in the CBT Examinee Guide: before the beginning of the exam, you have to read and agree to their terms and conditions within 2 minutes. If you...

Also a quick question about the NCEES Examinee Guide... Is there somewhere on the NCEES Portal dashboard that checks if you have read and agreed the examinee guide, before taking the exam? I know the examinee guide states that you are supposed to read and comply with the examinee guide before...

Here's a line-to-line conceptual diagram (Phase B to Phase C example) I drew up to try to help you. I learned this from Zach Stone's Electrical PE Review. If the line-to-line fault is Phase A to Phase B, use Ic1 and Ic2 in the sequence network circuit diagram. If the line-to-line fault is...

The best way for me to remember the sequence network diagrams are: Single line to ground: all 3 sequence networks in series Ia1 = Ia2 = Ia0 = Vg / (Z1 + Z2 + Zp) Ia = Ia1 + Ia2 + Ia0 = 3Ia1 Line to line fault: positive and negative sequence networks in series. Zero sequence is not included...

There probably will be some pre-test questions. I was looking at the NCEES examinee guide the other night for CBT exams, and I thought I remember seeing it mention a few pre-test questions for CBT exams that won't actually be counted...

Ziggy, Do NOT post anything at all about actual questions you encountered in the actual exam here. If you do so, you break the non-disclosure agreement you were supposed to agree with NCEES when taking the exam. They can cancel your score because of this. I'm trying to help you dodge a bullet...

Hey guys, I have a question while re-practicing the Cram for Exam questions. How does a grounding bank provide current to a load? See the attached problem 26 from Cram for Exam Vol. 3. I see their explanation that the grounding bank doesn't provide any power to the 1-phase load, but it still...

One minor question I have about looking at the electronic versions of the NEC, NFPA, NESC, etc during the exam: Does it feel more like looking at a PDF file through a browser rather than Adobe Acrobat or a typical PDF viewer program?

From my understanding, I think it's because you are asked to limit the MAX or PEAK charging current. Hence, you also have to use the MAX or PEAK input voltage...

Basically what the above two said. In synchronous machines (synch motors and synch gens), the synchronous reactance is typically given as Xs, which is an inductive reactance (think jX). To properly represent it as an impedance phasor: jXs There is also armature resistance Ra, which is the real...
