Residential low voltage wiring question

Question asked by rkranson on Oct 10, 2018

In residential, single family new construction, is it necessary for all low voltage cabling passing between floors, within walls or ceilings to be riser rated? Secondly, if low voltage cabling will be passing from inside to outside, does the cabling need to be grounded in a specific manner and within a specific distance to it entry/exit point?
