Good Article 5

[DTSMAN]

Here is a good article from the October issue of Cabling Installation and Maintenance magazine. I get the hard copy subscription to this and it always has good stuff in it.

Superior article. It's a "How Stuff Works" with a lot more seriousness and reality. Bootcamp for the neophyte.

I printed that out for my guys so they can see the results of a bad pull. It explains more in detail "why" you do it like this than I have been able to do.

I really liked that article also and am glad someone put it up as a subject.

Most of my clients when told about why they are having the velcro (or tie wraps)snug but not tight and un-evenly spaced on the cable runs understand but...
The only problem I see is with the combing of the cables because,let's face it,a majority of our clients want them to look neat in the data/server rooms.(maybe they will make a split loom of more deminsions to cover the ugly looking)?

Maybe if I take my copy of this issue around with me,it will help since it will show we are not slobs but have a reason for our 'madness'.

One the other hand,we could just suggest we install sheilded solutions as one of our options when doing the bids?

The article states-"The worst problem exists when excess slack is pushed back into a pullbox or outlet box, where very tight bends or even kinking could occur."

Please excuse the ignorance,but is there a proper technique for this? There always seems to be a tight bend behind the jacks after pushing the plate on the outlet box.

Well, what I do is pull out enough to terminate my cable and snap the jacks into the plate and then gently pull from the top of the wall to bring in the slack and snug the plate up to the box as closely as possible.

If that isn't right (no formal training here - all OJT and Tek-Tips) I would love to know what is.

That is one reason for no box in the wall to avoid this problem, just install the mud ring.

If you need or require one, use the large 4S box like the RACO 232. It gives you 2.19cu" of internal space.

This is something you need to specify up front to minimize this sort of problem. Electricians don't understand these types of requirements, until you explain them!

The question about "How much slack" has been haunting me for a while now so I broke out one of our BICSI manuals.

According to the Telecommunications Cabling Installation Manual under the Work area outlets section. It states that "Carefully coil the remaining slack (minimum 300 mm or 12") into the termination box. Do NOT kink the cable or exceed the bend radius of 4 times the cable diameter."

So it tells the minimum amount to leave (12") but not the maximum. If I find anything newer than this I will post it for everyone.

If afforded the chance in new construction, we request that 2-gang boxes be installed with 1-gang mudrings so that we have room to tuck away 4 cables of slack a little more easily.
