Here's what I've got for an errata list...
Morning #2: The answer should be 24 uF. They forgot to divide by 3.
Morning #4: They give us an efficiency of .85 in the problem, but solve using .80
Morning #13: Their # of cables in a conduit problem falls apart on this one. Just mark it out and forget it.
Morning #14: This one almost falls apart. The answer is right for the wrong reason.
Morning #22: They blow it in their addition/multiplication to find voltage.
Morning #28: So is it © as marked - .785 leading - or is it (a) as given in the answer ".785 lagging"
Morning #30: answer has an error in printing, but is otherwise OK (-j4500 on bottom instead of on top where it belongs)
Morning #35: solution printing error Eg=.8547-j.1935 - NOT j1.935 like they wrote
Afternoon #10: Picture is drawn so poorly I can't tell what they're trying to compare. They give us no dimensions on a magnetic diagram, we're just supposed to realize that there are 3x something involved.
Afternoon #22: This one gets a big WTF? Power flow in = Power flow out, right? Well, somehow, they get more power out of a system than they put in to it. 10+j15 in, 10+j15.36 out somehow. Sign me up with their electric company.
Afternoon #31: Stop the presses, zero sequence currents cannot flow in wye-connected windings. Says so right there.
Afternoon #38: They misplace the decimal on the current and everything goes down the crapper...
Afternoon #40: They use the 2002 NEC, similar but slightly different answer from 2008 NEC.
I'm sure there are more, but these were the ones I had marked in my book right now.
