NEC table 300.5 Column 3 says something about raceways needing to be buried 18”, but column 4, residential branch circuits, only need to be buried 12”. What’s the difference?
I am burying romex inside of PVC for the pool pump. 680.11 says, “...underground wiring shall not be permitted under the pool unless this wiring is necessary to supply pool equipment permitted by this article. Minimum cover depths shall be as given in table 300.5.
So, 12” or 18? Thanks.
