ECN Forum Forums Code Related Discussion NEC & other Code issues Places of Assembly 518-4

Here is the origin of my interest in this subject. A structural engineer stated that a 3/4" PVC conduit installed in a structural concrete deck had to be spaced 2” from the face of the finished concrete. He sighted NEC 518-4 as the reason for the requirement. The structural deck is in between a parking level below and meeting rooms above.
