I was doing the Example D5(b) and I found that for the Main Feeder neutral load, the calculation in D5(b) didn?t take into account 220.55. I checked my calculation (applying the standard method for the neutral) and every time I came to the same conclusion.
I?ve been struggling with this for two days and have no answer. I don?t know if I?m wrong, but, shouldn?t 220.55 be applied for this case?.
Hint: :According to D5(b), the Main Feeder Neutral load = 107,650 VA. This figure comes from D4(b), but D4(b) is served at 120/240 V (where 220.55 doesn?t apply), while D5(b) is served at 208Y/120 V. (where, I suppose, 220.55 does apply).
