PLFA run exposed horizontal above 7ft

[Jeffrey Brennan]

PLFA run exposed horizontal above 7ft across a ceiling need to be secured to independent support wires. At what distance intervals must a secure strap be placed. I need a code reference.

760.130(B)(1) says that cables shall be adequately supported. You decide what adequate is.

Is there a clear NEC/NFPA definition of “Adequate” & “Supported”?

 

[infinity]

Some places have local amendments, in NYC the maximum distance between supports is 5'.

 

[Jeffrey Brennan]

Ok. Is there a clear NEC/NFPA definition of “Adequate” or “Supported”?
