I am running cat6 cable at a job. I was wondering if anyone knows how many calbes can be put into a 3/4", 1", and 4" pvc conduit that the electrician is piping in for me. Heading into my closet I will have about 160 cables. He is proposing 2-4" conduits. Will that be enough?

p.s. Where can I find documentation on this?

Thanks,

Doubled
