Passed! Merry Christmas! For those that didn't make: Keep it up (after a little rest)!

Found out they never processed my take-home exam, which I completed right away... arrrrrrrrrrrrgh... My confidence in passing is slightly restored :)

Matters to me! Mine still says EI. I'm less hopeful about what I find in the mail when I return to Oregon next week... I'll try the GA Tech class this time around.

Well it's $475 for the application fees (in Oregon), so you had a tight budget for study materials or your state is much cheaper.

Anybody who passed - do you see any update at the Oregon PE License Lookup?: http://www.oregon.gov/OSBEELS/Pages/Search_License.aspx

They update the License Lookup on Fridays. I had a job interview yesterday and could have really used the news, but the Oregon board is still living in the 19th century and only allows communications by mail... You'd think they'd have procedures that enhanced Oregon engineering prospects.

Well I passed!!!..... the OSBEELS take home examination :( Now where's my PE result???

I found this: "" In a three-phase bank, the delta/wye connections are internal to the bank, and are already accounted for in the voltage ratings (i.e. the sqrt(3) is built into the nameplate data on the bank). If you are hooking up three single-phase transformers you have to take the delta/wye...

So I am now assuming that (1) for a D-Y transformer bank N1/N2 = VLL1/VLL1, whereas (2) for 3 single-phase transformers (in a D-Y configuration) N1/N2 = VLL1/VLN2. Can someone briefly explain the reasons for (1)? Is the intention of "ratio" to calculate VLL/VLL, rather than actual turns ratio...

Even if the secondary is Wye (L-to-N)? So the ratio is not actually a ratio of turns, but only the ratio of VLL/VLL???

For a D-Y (Delta-Wye) transformer, does turns ratio refer to the actual turns ratio (and VLL-to-VLN), or to VLL-to-VLL ("apparent turns ratio")? The problem requires a calculation of low-side voltage, through a D-Y transformer with 10:1 turn ratio. High-side voltage is 4600 Volts. The...

So Table 9 gives R and X for 3-phase. And Table 9 gives R and X for 1-phase, but you multiply by 2 because of the return path (Correct?). Seems odd that 3 phases would have the same impedance. Is this because we're only using the impedance in per-phase calculations? (same as how current only...

NEC TABLE 9: Alternating-Current Resistance and Reactance for 600-Volt Cables, 3-Phase, 60 Hz, 75 C - Three Single Conductors in Conduit Stupid Question: What about AC SINGLE-PHASE (Single) Conductors? Is there a table? Thanks!

I thought we multiply by 1.25 to get the FLA of a CD (continuous duty) motor, but that doesn't appear to be the case. When do we multiply by 1.25? And why don't we here? So I calculated: 65 Amps x 1.25 x 1.15 = 93.4 Amps (65 Amps from NEC Table 430.250) (1.15 from NEC 430-32a1) The correct...
