While the NEC contains the phrase "engineering supervision", the national building codes do not.
The national building codes including the NEC portion are simply a set of prescriptions.
You either follow the prescription or you have an engineer deviate from the prescription and stamp the plans.
Conduit fill is a prescription. An engineer can deviate from it.
That again is false.
Sorry George your PE seal does not make you all powerful.
You still must follow the NEC, at least in any of the 5 states I work in.
Where is it that you work?
Here in my area the building code has nothing to do with the NEC.
