Has this table changed between 2002-2005? I've been using Stallcup's Master study guide and a question has me stumped. Here is the question "Rigid metal conduit should be buried in the ground at a minimum of __ inches?"
A)4 B)6 C)12 D)18
I am coming up with an answer different than what the study guide says I should get using this table. I am using a 2002 code book,but a 2005 study guide.
Thanks
Nathan
