For PE Power, I highly recommend Zach Stone's Electrical PE Review. Also check out Engineering Pro Guides.

I haven't been to Batavia, but I know of it. It's just east of Buffalo, which I have been there before.

Lately I've had an interest in places in New York State other than NYC. I like to explore on Google Maps.

With pf = 0.95 lag, the power angle is 18.19 degrees. power angle = voltage angle - current angle If the voltage angle is referenced as 0 degrees, then current angle must be -18.19 degrees. 0 - -(18.19) = 18.19

In general, as you said the line-to-line voltages lead the line-to-neutral voltages by 30 degrees. This is assuming a balanced, positive-sequence ABC system. If the phase angles are not given, usually (arbitrarily) Van is referenced at 0 degrees. Vab leads Van by 30 degrees. Vbc leads Vbn by...

2 highly recommended practice exam sets: -Zach Stone's Electrical PE Review -Justin Kauwale's Engineering Pro Guides, PE Power

Because for 1-phase circuits, there is current going both to the load (through the supply/hot conductor) and then back to the source (through the neutral conductor). So both conductors have a voltage drop because of the current (V = IZ). In a balanced 3-phase circuit, only the supply/hot...

Luminous flux is in lumens (lm). Illuminance (typically called E, although I guess the NCEES reference book uses I) is given in footcandles or lux. Footcandles (fc) is lumens over square foot (lm/ft^2). Lux (lx) is lunens over square meters (lm/m^2). So I guess one way to look at that NCEES...

It's been a bit of a long time since I posted here with solutions, so I am a bit rusty. Attached is what I have. For lighting illumination problems, I prefer using this formula I first learned from the Complex Imaginary PE Power exam sets: Luminous Flux = (FC * Area) / (CU * MF) It may also...

We highly recommend Zach Stone's Electrical PE Review and Justin Kauwale's Engineering Pro Guides.

If anything, I would just use the Camara books for the 2 practice exams at the end of the books. I would not use it for studying content. (This is the first time in a long while that I'm posting on this board.)

Backing up what Dothracki said above, I highly recommend doing Zach Stone's Electrical PE Review full (80 questions) practice exam and Justin Kauwale's Engineering Pro Guides exams. Without giving too much away, these practice exams are pretty (fairly) difficult for those who are just beginning...

Sorry to hear about these issues you're facing. Best of luck in your exam! Do what you can to persevere and stay strong.

Good luck! Feel free to browse this forum and ask for help when you need it.

I would say maybe take a day or a few days to work on practice problems that specifically refer to the NEC from the practice exams you have. Do them repeatedly until you are comfortable at least with the typical NEC sections (mostly Articles 210, 220, 240, 250, 310, 430, Chapter 9 Tables off the...
