center screw on phone junction block grounded ... why?
In my house the phone wires come into the basement (from the
externally-mounted demarcation box) to a junction block that looks like this one: http://thisishowweparty.com/img/dmarc1.jpg (This isn't mine, it's illustrating an unrelated post that I happened to find. It's also referenced he http://www.dslreports.com/forum/remark,23986992) On mine, the phone wires are joined under the outboard nuts. On the one in the picture, there aren't any phone wires. But on this one, as on mine, the centre screw is grounded (on mine, to the copper water pipe, near where the electrical service is grounded). But the block is of some composite material and there is no obvious connection from either wire terminal to that centre screw. So what the heck's the point of grounding it? I'd like to remove, or at least relocate, this block and modernize the phone cabling.Are devices like this still current? If not, what's the "current" correct replacement device? Thanks, Chip C Toronto |
