Support of low voltage cables.

[lknight]

NEC Section 334-10(a) requires MC cable to be supported and secured at intervals not exceeding 6-ft. Is the any such requirement for supporting distance intervals for low voltage cables such as fire or communication jacketed cables?

 

[hbiss]

No- although it must be supported independently. It cannot be supported by any electrical, plumbing or sprinkler piping, nor HVAC ductwork or equipment nor from ceiling support wires or the ceiling grid.
