The NEC considers pipe to be adequately protected when it is either under, or even with, the bottom of the slab. I'd like to open this topic for discussion.
Many times, foundations/slabs in industrial buildings, and restaraunts, will be cut to install or replace air, water, sewage, and drain lines. When this happens, the guy operating the saw will typically set his cut to just a little past the depth of the slab. When this happens, and the conduit is installed "per code," wires get cut.
I propose that even burying the pipe an inch or two would make a big difference in how many repairs need to be made.
Your thoughts?
