Can anyone tell me what SBCCI stands for?, is this test harder than a regular Journeymans test. Does it allow one to work in several or all states?

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 [Linked Image] ..
Anywho here is a question that was on the test That I kind sorta had to just take a stab:
[Linked Image] 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?????

Sean, Assuming that answer D should read "Does not require a grounded conductor" then that would be the best answer. If a motor doesn't need a neutral, you don't have to run one. But if it said "Does not require a ground" as you typed it, then the best answer (I think) is 250 kcmil.

Don't be concerned about those punks finishing early. They probably made a lot of careless errors and you probably just made sure you had the correct answer before you filled the bubble.

Back in school, I was so hard on myself that I had to not only get an A (or preferably, a 100%) but I also had to be the first one finished.

Boy, how things have changed since then!
Now I'm doing good to just pass!

I think the answer is D.
I don't think there is enough information to determine a groundING conductor size without knowing the type, and therefore rating, of the OCPD.
Correct?

I am aware that three phase motors do not need a neutral. the last option was "ground" not "grounded conductor".
I remember coming across a FPN that said if a neutral is going to a 3 phase motor (presumably with some type of MCC equipment)that requires a neutral, It shall be same size as phase conductors.I will post my results of the test when I get them [Linked Image]
