I don't have my code book handy at the moment but does anybody know the table to use for calculating cat 5 fill in a conduit? I came across this tonight while scoping out a job. ( 10 cat 5 in a one inch conduit )
Wacked, Data conduits often live by there own rules, but as I recall, 10 cables need about a 1-1/2 conduit, junction boxes every 100 feet and after every two 90 degree bends. Im fairly sure that there is somebody out there who is much smarter than I am who can quote the source. If you have to pull the cables, they pull hard unless they are a slick finish on the jacket. Try Google. Good luck, Larry
According to a conduit capacity calculator from ADC/Krone 7 Typical 4-PR @ac .25" OD. in a one inch conduit. This would assume no more then 40% fill to allow for reasonable pull.
Today we completed a job of installing conduits and cat3 cables for the hospital. Telus and the IT department wanted required 4" EMT with four 100 pair cables pulled in. This was 40% fill.

"Will it be cheaper if I drill the holes for you?"
I answered this in the other place you asked. 12-1014 Give the rules for wire fill in raceways and the type of load has no bearing. %40 for more than 2 cables up to 200 cables max.
