Well, I had the test this morning, along with about 15 guys. I was one of the last 5 to finish. The young guys(<20)were through with an hour to spare
..
Anywho here is a question that was on the test That I kind sorta had to just take a stab:
a 480 volt, 3 phase service feeds a disconnect that has only one motor on it fed by 250 kcmil, what size grounded conductor does the NEC require to this motor?
a.250 kcmil
b.1/0
c.2/0
d.does not require ground
anyway, whatcha think?????
