elect. conduit in a 2" slab?
hi all,  is running a 1" rigid elec. conduit in a 2" slab on steel decking allowed?  this will leave 1" concrete cover only.  would that be a shrinkage crack problem?  what code should i refer to?  thanks for your help
check out our whitepaper library.
not a good idea.  one inch conduit has an o.d. of 1.315.  this leaves only about 5/8 inch of cover.  plus aci section 6.3.5.1 doesn't allow an embedded item larger than one third the slab thickness.
its going too crack, why not run it below the pan
