HI Bob, I am looking at tabel 110.26(A)(1) right now, and how I am reading it is that the minimum clear distance is 4 ft, based upon the voltage you have given, and that you are in condition 3. I could be wrong, but this is how I understand what I am reading. What book are you getting this question from if you don't mind my asking?
