3/4 to 1/2 just before an instrument in a class 1 div 2 area I know the answer just cant find in code book
Expert:  Steve G. replied 2 years ago.
I'm doing this from the road and I don't have my code book at hand but it's going to be in article 500.
I will opt out of this question which will allow other electrical experts to chime in with the full answer.
Hold on.

Hi, I'm Mike and I'll be glad to assist you. You may use a 3/4" coupling and a 1/2 to 3/4" reducer to do it.
Customer: replied 2 years ago.
What article says you can reduce conduit size in a coupling in a class1 doc 1 area
Expert:  Mike G. replied 2 years ago.
There isn't an article that says you can't. As long as you are in pipe is the only concern.
