Just got an NCEES email saying October PE exams are canceled.

[Tim - formerly @ NCEES]

I passed along the comments and heard the following back from our exam development engineer and publications manager:

This item was updated from the 2017 PE Power practice exam into an alternative item type (AIT).  Option A has now been revised to eliminate any confusion. You can see the revised version in the free preview on ncees.org.

Just checked and it now says positive-sequence for Option A. That was a quick update!

Looks like all that effort into my Bible binder just went down the drain!!!

Anyone else got this email? Thoughts? Opinions?

As the topic title mentioned, I just received an email from NCEES stating that:

"NCEES has accelerated the PE Electrical and Computer Power exam transition to computer-based testing (CBT). All examinees who are currently registered to take this exam in October will be canceled and automatically provided a full refund of their exam registration fee so they can immediately register for the computer-based exam."

Next time please mark this as PE Electrical. Here i am studying for the Civil Transpo exam and had a big ole heart attack and dirty pants because i read this header 

Edit: Apparently I'm blind and cant read that this was under the power forum. Carry on

Exactly. Imagine how we feel? I have a solid 8 months studying for this stupid test that I'll never get to use these 30+ books on.

Hi @Tim @ NCEES, I've found a few mistakes in the new NCEES® Power PE Reference Manual for the CBT exam. One of them is a formula mistake with the variable in the wrong place that will result in a wrong answer for anyone that uses it.

Who can I can notify at NCEES to help bring this to the right persons attention?

Thanks Tim, will do.

Hi, 

I have noticed one comment in the reference book page# 65, I would like to share it with you before we escalate it to NCEES. 

The equation to find the capacitance is C=Q/pi*f*(Square V)

but if you start analysing the equation from reactive power you will get: 

Q= (Square V)/Xc  where Xc=1/2*pi*f*C

then 

C=Q/2*pi*f*(Square V)

So, as shown number 2 is missing in the denominator of the equation which mentioned in the handbook.

Is my analysis above correct?

Not totally sure on your question @Mohammed Ahmed but on page 63 they have a formula with the 2 in it under "the relationship between capacitive and reactive power".

No idea why they change notation and have Preactive in one spot and q in another spot and the MVAR in another spot? 

It's like they gave an intern a stack of books and said "copy paste formulas and diagrams for these topics into a file"

I attempted to solve some problems with the handbook today, and it's just missing so many little things, or it uses really complex formulas for easy stuff - like the above situation.

I did send a feedback letter to NCEES and got a very concise response to my concerns, and that they are aware of the rumors that protection will be hard because it is not in the reference book.

Yes your math is correct, but you need to pay closer attention to what is specified in the reference book. Notice on page 65 it says "V_line is the maximum value of the sinusoid." For the other formula you were using V is assumed to be RMS. 

Remember



And



Substituting



That's my best guess as to how they arrived at their formula.

Thanks for clarification.. to avoid confusion I would recommend to mention in the equation Vmax instead of Vline.

Hi everyone,

Should we print the NCEES Reference book out and using it for the exam? How about NFP70? I got two types of email, one of them said I should print it and bring it to the exam (Texas board) and another said I don't need to bring anything (NCEES). I really confuse? What we should to do? Thank you

If I were you I would email NCEES stating that Texas is informing their applicants to print out material and bring it to the exam to confirm if that is an accurate statement or not. You should be given access to the reference book as well as NEC, NESC, and NFPA 70E in PDF format on the exam according to NCEES.

I got this email from NCEES about my concern.

Hello,Thank you for your email. This exam is computer based and a closed book exam. https://ncees.org/pe-electrical-and-computer-power-exam/The reference handbook will be provided to you at the testing center as a searchable document on the computer. Here is a copy of our Examinee Guide. Please review it before your exam.https://ncees.org/exams/examinee-guide/

Correct, this is what the exam specifications state. https://ncees.org/wp-content/uploads/Power-Dec-2020_CBT.pdf

Maybe Texas didn't get the memo about the change to closed book CBT?

I printed both and put in a binder. you never know. Ive done practice questions where ive needed nfpa70

oh wow

Thanks Tim, will do.

Zach, did you ever hear back on these issues?

Zach, did you ever hear back on these issues? 

Yes, I contacted NCEES per @Tim @ NCEES's instructions. They said they are working on revising issues.

This is a great community. I have a question about the NEC version to use during the exam.

If the 2020 NEC was released this year, we were able to still use the 2017 NEC for the exams administered in 2020.

If I schedule the exam on December 2020 can I still use the 2017 NEC?

If I schedule the exam for January 2021 does that mean that I have to get the 2020 NEC?
