I need some guidence on this. I had this code quiz i was taking. There was this question I could not find an answer to. The qeustion read this way. What is the minimum height for 277 volt to ground fluorescent light fixture in a tunnel. The choices were 10ft,12ft,18ft, or 20ft and what article and section I found my answer in. Anybody got a clue for this one. I was all over410 lookin for it. any help would be welcome. :confused:

I think the answer, given the choices, is 18'. However, I think the question was worded incorrectly. It should have read "greater than 277V". I don't see any height restictions for a tunnel, 277V, and Fluorescent luminaires.

Re: 277 volt lighting

I think it's a trick question
from options given i select 10 as thats the min of the choices
210.6 c covers the 277 volt fixtures
The master exam i took had some of them trick ???
they put extra values and words in a question that have nothing to do with the answer.
