ECN Forum Forums Code Related Discussion NEC & other Code issues NM above 3 floors

I've heard this but have never seen it in the 'book'.
My understanding is- Nm Just cannot RISE more than 3 floors.
Once a proper riser has been installed,NM can be on the 14th floor. so long as it is not above a dropped ceiling and the other such rules.

Guidance please.

Thanx
