Fire alarm cable????
Fire alarm cable????
This is creative.
I hope not. It looks more like a piece of THHN used to tie the lights up and secure the mc.
I didn't know THHN had a rated tensile strength.
(some sort of marking is NEC required)
Only if it's located within the cavity of a fire rated ceiling.
I agree, or if I just don't want the ceiling guy using my tie wire. I usually paint it fluorescent orange while its still bundled regardless of the ceiling type.
If the cables are 6' or less they didn't need support anyways.

It looks to me like 12 AWG Steel tie wire painted red (some sort of marking is NEC required) it also looks fastened at both ends as required by the NEC.
