This question came up in class?

"If the EMT has the supplementary protection what is the burial depth?

I suggested table 300.5 column 3 which is for nonmetallic raceways and other approved raceways.

what are your thoughts and comments on this questions?

I know from experience that EMT in direct contact with the eart doesn't last.

Thanks.
