Does Flex need to be strapped when fished through a drop ceiling?

Dropped ceiling with removable panels just means laziness...

Laziness? Having to open every tile on a 100+' run is alot more then opening 3 or 4.

I do not believe for a minute that the inspector will agree that a suspended ceiling run is 'fished'.

IMO you will have to support the FMC off the ceiling.

I agree with e57.

To put things in perspective.
100' run- 4' tiles= 25 tiles. Open every other one to strap means 12-13 tiles opened.

If tiles are 2' long then you open every 2-3 tiles, 15-25 opened. Whats the big deal. Leaving flex laying on tiles is lame. It's bad enough when the LV guys do it.

I believe the NEC now requires even low voltage cables to be supported in dropped ceilings. I don't think laying the cables accross the grid is acceptable anymore.

Every 4.5' would be every tile. It was not fished just straight across the tile but over whatever was available to support it without getting in there.

We just went thru this with a store, the LV guy fished the camera cables, no permit, just one problem the fire, and construction offical were in the store at the time, finally they caught a live one, the store owner was not very happy, paying to have it done right.

Probably a better question is why are you using 100 feet of greenfield in one run?

And if it was piped in say E.M.T. it would only have to be supported every 10'. I have to agree with everyone else here, do it right the first time and support the flex to what the code calls for. Good luck.
