Just how far can you run 2 inch emt (set screw couplings) with no pull string with 3 90's and not exspect to get killed ?Any fish tapes go to 400 feet ?

For data??? 400 ft??? Are you sure??? Data lines, usually cat5E, hell even cat 6 are not good for over 300ft. Anything over that they usually run fiber optic and link severs together. Seems WAY to long to me from my experience.

I doubt that you can pull data cables in and out of a C without damaging them.
 
Jim,
Take a look at the specs for the cable. I have seen a lot of specs from the manufacturer that said no more than 100' between pull points and deduct 30' for each 90.

Actually i was not using it for data ,just borrowing it for tempary service.Looked like easy solution but wasnt.Seems like there should be a rule in nec to cover raceways like this.

I think Article 358 covers it. :grin:
I can't believe my ears Jim wants a rule added for this. Shocking. How would you phrase the rule " if there is abandon conduit that is to long, to high, and in a really bad spot, thou shall not use it." :)

I was thinking of something along the lines of.....

"All installations shall be installed so as to ease any future installations or modifications of existing from the use of a comfy rolling chair"
 
TIA/EIA 568-B: A maximum horizontal-run of 100 meters (308ft.), including work station and communication closet patch cords.

and i think the max the actual cat5e cable can be is 296'. You can have an additional 12' in patch cables.
 
Actually i include phone along with internet as data.In this case it was to the phone equipment.My beef was that installing 350 feet without a pull box or jet line makes a disaster for the next man.Cant very easily suck a line thru 35 set screw couplings unless you tape every one.Would been easy before other tenants moved in.Was lucky i could get a lift in there to fix it.
 
I've seen documentaries on TV showing that some very long conduit runs were strung using guinea pigs, ferrets, rats, rabbits, or a similar sized animal to run the first pull string into a very long conduit ( at a particle separator, collider, or military site or something like that - I don't remember what it was).

Get yourself a pet!

Actually a small wheeled motor driven battery mouse is what we needed.
 
I don't see what all the fuss is about, runs like this are pulled every day. If

you can't blow it or vacuum it in, use two fish tapes, SOP.
