ECN Forum Forums General Topics of the Trade Voice - Data - Video Discussion cat 5 conduit fill

take OD x OD x .7854 of each Data or Cable that well get you the Sq. inch for fill calculations. Then go to Chaper 9 table 4 Percentage fill charts .

Example 6 cad 5 at .25 dia.(what ever the Dia. is)
.25x.25x.7854=.04908
.04908x6=.2945
3/4 emt at 40 % fill (see Chaper 9 table 1)=.213 to small
1 inch at 40 % fill =.346 so I'd use 1inch EMT

Works for me.
