... Hi Hank Since your doing a full gut rehab anyhow! Here are a few ideas that we often do during upscale renovations. The cost is negligible before the walls go up. In the den, we run a 3/4 PVC conduit from a pull box in the den, both upwards to the attic and downwards to the basement for future unknown technological advances. We sometimes do the same thing in the master bedroom. All homes are daisy chain wired to every room with two 4 wire telephone and two 6 wire shielded cable each in their respective pullboxes, plus from the central utility area two 75 ohm coax are run to a pullbox in each room. Gary The usage of a pathway (conduit, etc.) is always a good idea for future additions for your structure home cabling (especially heavily used areas) "Daisy chaining" is NO longer the acceptable physical installation practice for home structured cabling (EIA/TIA 570-A standard). This was the practice by the Bell Operating companies for telephone cabling before its breakup in 1984 .. and is mentioned as a legacy method used before the adoption of the EIA/TIA standards. The standard also addresses 75 ohm video cabling (TV, etc.) as well as have foundation standards (568 and 569) more suited for larger commercial or business installations. The standardized practice for structure cabling in new installations (and remodeling or major retro-fits) is for "home-run" wiring from each outlet from a central location (cabling in a physical star topology) with a distance limitation of no more than 100 meters from equipment to the telecommunications outlet. BICSI also performs certification of structured cabling installers (electricians, contractors) for both residential and commercial installations. Do a Google search on EIA/TIA 570-A ; structured cabling or BICSI and you will find the necessary information. The major cabling vendors (Leviton, Systemax(old AT&T cable), etc.) also have this pertinent information. I only point this out, since I am a professional consultant in this area --- and find the "daisy chain" approach for physical cable installation still practiced and approved by municipalities and contractors ... UNAWARE of these standards ... now 10 years old and reviewed on an annual basis through the EIA and TIA organizations. gb |
