Almost 2 weeks and no foolow up posts from rbrick33????
commercial or residential setting
commercial or residential setting
I did install a 100 amp subpanel in a pole barn used by maintenance personnell
and install 8 outlets on the walls. I did not install a gfci because i knew that it is not considered residential only because it is in a residential apartment property and only used by maintenance personnell. The NEC does not say anywhere that i can find that gfci's are needed. I know that it would not hurt to install a gfci anyway but the point is that the inspector is enforcing the code.... but where is in the code? he failed me, so is he right or wrong?
A little help will be appreciated. Please use code reference.
Thank you.

Mad Max: You are asking a question that is not related to the topic of this thread. It is also not related to the topic of exam questions.
Let me suggest that you start a new thread in the area of NEC issues. You are more likely to get valuable information and opinions, if your question is not buried in an unrelated discussion.
