The question asks you to determine the appropriate size UF Al (60 degC) conductor using NEC for a 3HP continuous duty motor. I understand the load amperage is 25x1.25=31.3A. Using table 310.15, an 8AWG conductor can carry 35A, which is what I selected since its greater than FLAx25%. However...

The questions asks for the average value. Should'nt the answer be 0 and not 1000? The average value of a periodic square wave is zero. The answer would make sense to me if we were asked to find the effective or r.m.s value of the waveform. What am I missing? Thanks.

Does anyone know why the solution assumes the primary and secondary winding resistance are equal? I would expect the secondary to have more resistance as it effectively has more turns. So Rp is not equal to (a^2)Rs ?

Just about to start preparing for the October PE Power test. I noticed the Camara power reference manual covers some topics that are not specifically listed on the NCEES exam spec. For example, communications theory, transistors, to name a few. The exam spec states "The knowledge areas...

On average, what percentage of exam questions will be asked in metric units? I've heard that we have the option of solving problems presented in imperial in either metric or imperial. Is this true? Also, are we provided with a sufficient amount of scrap paper to work out problems? Thanks.
