Hi, All:
I have been a lurker here for some time and finally got connected today. I am in full agreement with Hal's way of thinking. I've been working in the electrical and telecommunications industries since 1974. I like to think that I know what I am doing. I've also learned through the school of hard knocks.
Structured wiring systems sound like a great idea, but they really are just marketing. It's just another "ooh, ahh" box on the wall in the basement. The typical home owner has absolutely no clue what it does or how to use it. Nor does the cable, telephone or computer company. If anything, they complain that the "other guy" was in there. They are way to congested for standard practices. There is way too much effort being spent trying to reinvent the wheel.
Bear in mind, the manufacturers of these panels set their own standards by offering their own training, or as they like to refer to it "certification". Send me to a one-day class at the local Holiday Inn or an on-line course to learn how to become a master electrician and I might buy into that strategy.
Truth is, you cannot possibly learn all of the intracacies of any trade through something as simplistic as "EZLearn". Manufacturers lead contractors and end users into believing that whatever is in the bottle they are selling is the thing that you must buy. It's not that simple.
How about testing for imbalance on a circuit when using these systems? How about locating causes for ring trip? Do these classes include the necessary (very expensive) test equipment? How about testing for other things, like jitter, latency or slips? There is SO much more to the telecommunications industry than pulling a cable and terminating it. If you can install it, but you don't know how to fix it, are you really doing your customer a service? Nope.
Most low-voltage trades, as in telecommunications, CATV, video surveillance and alarm really do prefer that the cables be left for them to terminate. It makes no sense whatsoever to force them to have to create transitional connectivity to make the structured wiring system work. Smurf tube and perhaps some empty conduits or pull strings are usually all these guys want and they are happy to get them. I can assure you that I would much rather encounter a house full of pull strings and empty conduit than any structured wiring system can offer. Remember the old days when the local telephone company mandated the appropriate number of empty conduits with pull strings that needed to be installed and where? Why does everyone seem to be in such a hurry to run away from something that was so simple and still made money?
I have a pile of modules from various structured wiring panels sitting in my office that have failed. We could not obtain replacements. One was made (or marketed) by IBM! What did we have to do to restore the customer's service? Perform temporary splicing to restore service with Scotchloks, make a dozen phone calls and an equal number of Internet searches, only to tell the customer that it's not available and the temporary solution is all that can be done. I might also add, Verizon won't touch these things whatsoever, despite the fact that they sold them in their new home wiring packages. This, even if the customer pays extra for inside wiring maintenance.
Has anyone here encountered that situation where they need to find a main breaker, oh just let me be creative here, for a 200 amp Pushmatic panel? You immediately shake your head with a resounding "YES" on that one. It's the same thing with structured wiring panels, only worse. Every one of them is unique, most don't offer any interchangable parts, and the manufacturers change design regularly. Leviton's panels won't support anyone else's "fufu" module, nor will Suttle's, ICC's, Hubbell's or the myriad of imported no-name "systems". What happens when the local supply house chain stops carrying Leviton and switches over to Cooper (Eagle)? Special order time through another supply house.
Sorry to come in here with such a bang, but in my 30+ years working on both sides of this debate, I think that I know what works and what doesn't. I am sure that I may have rubbed some folks here the wrong way and for that, I apologize. I hope that's not the case. I am just trying to offer some perspective from the other side. I must say that I am very happy to have finally picked the lock to this place. There sure seems to be a lot going on.
