Nobody has any questions about Fire Alarm Cable or IT cable requirements? I sure do

    Surprise that several links or articles aren't listed in here concerning the requirements for low voltage cable which is predominate in all buildings. The Fire Alarm, IT lines, Thermostat wiring, Energy Management/ Controls, etc. all have requirements that the general building official or building department don't look at or care about since the majority of this type of work doesn't require permitting.

    Securing of IT cables is my big problem - they lay in on the ceiling grid and when the grid gives way in a fire, the cable drops and entangles firefighters - several document cases of fire fatalities have been associated with entanglement of low voltage wiring.

    If somebody or someone has a few links/ articles, or comments they would like to share _ I am sure that everybody can learn something.

    Thanks !

    LV cable for any use is regulated under the NEC and we inspect if regularly. J-hooks and straps are used frequently. Nothing is allowed to lay on a drop ceiling grid or be attached to conduit.

    Builder Bob, ...I feel your pain !........Around here, whenever it
    is mentioned about not laying the cables & other types of wiring
    assemblies on to the ceiling tiles, ...I get ignored and "what the
    heck are you quoting Elec. Code to us for" look..........Little to
    no enforcement of the NEC regarding this requirement.

    See Article(s) 770.110, ...770.133, ...800.133, ...820.110 and
    others, in the `17 NEC.

    Many times they have install low voltage or fiber cables in on going jobs without it on the plans. "We don't need no stinking permit".
