calculate bundle thickness

[charliebarns]

I am sure somebody posted a link to a calculator to work this out but I can't find the thread, can someone help? I'd like to calculate my bundle diameters as I've discovered the channel vision cans, although they have an 1 3/4 knockout, will only accommodate an 1 1/4 bushing, which seems small.

Thx

Can you use more than 1 knockout?

Can you share why you like the Channel Vision cans?

I have a Leviton that I may return.

I could but they've spaced them a bit strange and I wanted all the wires to come in on the side. Also, I wanted the plexiglass doors. I may start regretting the purchase. I can fit 1 1/2 conduits into Leviton boxes no problem (my current home) but 1 1/4 seems very restrictive. In one box I've got 124 RG6QS to come in, can't get that through 1 1/4 hole... -_-

Do you absolutely need to use the side holes? The CV has the huge rounded rectangle opening at the top where you can bring in more wire than you know to do with. It can be routed nicely with finger channel on either side of the can. Maybe run some wire thru the top to feed top part of box and the lower bard of can thru the side holes? Just another option...

Freaky timing Charlie.
I was just looking for the same equation yesterday. The best I could fine is a table here http://hydra.nat.uni-magdeburg.de/packing/cci/
It works backwards: given a ratio of cable diameter to bundle diameter, how many cables will fit?
So for cat5, your ratio is 5 (1.25" / 0.25")
Take that to the table and look down the Ratio column until you find 5 and read from the left column that it will hold about 19 or 20 cables.

I estimated that my bundle of 300 cat5, cat6, 22/4 and RG6 cables is going to be around 5 inches in diameter! -_- Or four 2.5" bundles.

What cans would you buy, if you had to do it again?

Do the CV enclosures' mounting holes work well with the Elk products?

How about the Leviton modules?

Thanks to all for the response. This is how it worked out (so far). Calculated bundle thickness to need 3 1 1/2" knockouts, mounted the cans, absolutely no way I'm getting all those wires down my measly knockouts! Took Steve's suggestion and knocked out the big sucker in the middle...all is well
