You can apply derating on 90c table values but the final cable ampacity can not exceed 75C rating for the given AWG.

In your example, assuming infinite primary fault current the secondary fault MVA would be .750 MVA/% Z, let's say 5% transformer impedance = .750/0,05 = 15 MVA You can use MVA method too. let's say the Fault MVA on primary side is infinity(99999999 MVA) and transformer fault mva is .750/.05 =...

Some calculator may require little screw driver to pop open the cover to replace battery, not sure if exam would allow this as this may be considered as weapon. I replaced the batteries at home , took two calculators to the exam. Without calculator you fail the exam. Importance of calculator is...

I relied to look more in my notes on topics such as reliability, NEC code problems, megger, insulation testing  etc, something you don't do everyday and has a tendency to forget. On other regular electrical engineering topics such as Power factor calculation, Wye/Delta problems, Per unit...

The way to remember this is FLC - C means code value FLA- A means actual values, name plate values.  For sizing conductor, use the FLC values, the reason being if you change the motor etc, you may not change the conductor, so that has to be the worst case value. Due to efficiency, different...

That's what prompted me to ask those questions. 

And how could you even qualify to take FE and PE, without EE degree and or EE experience? Don't you either have to have a qualification or practical experience? for board to approve your application?  

Don't go there Man!😫 You sowed a seed of doubt in me now and I'm frightened. I never knew there is such a thing of audit and going back. I thought once a pass, then pass, even if they passed you in error then it is upon them not on you.  I thought we are only responsible if we made a mistake...

If you have the time, it won't hurt to go through spin up. I know many people think it is repetitive and on easier side and I agree. Exam is not always all about tough questions, sometimes simple questions trip us. If you are too comfortable with spin up, then do 2 or 3 practice exam, skip some...

So the bottom line is process is arduous. Far and few would put themselves through this process. Shouldn't we start earning $10-20K more than before? I haven't seen that light bulb moment yet. 

Going through application process, FE , PE , long wait for results, requires a lot of energy and dedication. One should do this when they are relatively young. One does feel relieved  after they pass.  

As I was going through the exam, I thought it would be kind of cool to keep in touch with the PE material such as fault analysis, PU, PF correction, voltage drop etc etc even after I pass, so you don't forget.  After 2-3 months of passing,  I don't want to visit the PE material. I will visit...

I found this to be way overkill for PE exam. Might be a good reference book for an EE but I did not think it would be helpful for PE exam. I bought it and then returned it after a week or so.  

I'm coming out of self exiled mode. The person said they weren't posting in this forum because I was annoying them. I have not posted for two months and that person isn't posting either.  We always need some or the other excuse. Sounds familiar, "because of you, I'm not doing this....".  To...

I believe Z(old) and Z (new) is confusing and I believe I brought it to Justin's notice . Z old in the 1st line should be Z new. 2nd line, Z new and Z old values do not match.   Go by the basic formula  S = (V^2 /Z) S1 = V1^2/Z1 and S2 = V2^2/Z2 subscript 1 = 480 volts or old voltage 2= 400...

You would need this sub forum more than me. So I think you should stay here and I won't post any more in this sub forum. All the best. 

Hey guys, I passed my FE and PE from NY board. My undergraduate degree is from a foreign country, so I didn't do a degree evaluation and even without points for degree I had about 20 yrs of industrial experience which qualified me for Power PE in NY board.  Will I be eligible to transfer my...
