Hi guys… I'm going to be Installing PVC conduits for 4160 volt under a new floor slab. These conduits will be 32 inches deep.....22" fill......10" concrete slab.
Do I need to concrete encase these?

Look at 300.50

Do you have specs that say you have to?

I will look at that section tomorrow… thanks...Left my book in the trailer…
I don't have specs on this because we are offering a credit to use PVC rather than PVC coated rigid( original spec) in this area. The customer rather use this money elsewhere on this project with us.

This is all with the engineers approval of course. I'm sure the engineer will want concrete encasement. I'm just curious if it was required.
