old house cable wire fishing
Comments (7)> where does the second output from the current splitter go? That is a fascinating question. Thanks for asking, prompting me to take a look. There are three outs. - One of them them goes upstairs to the shark fin cable modem in my office. - One was a wire to nowhere, likely for when the previous owners had a TV on the first floor, which we do not. - One is a mystery. It goes to a black modem marked Touchstone Telephony Modem (Arris). There don't seem to be any wires coming out of this, and I'm not exactly sure what it is. My guess is that a couple years ago, we briefly signed up for a package cable modem/telephone service, but the quality was so bad that we canceled it after a couple weeks. I wonder if we got a free modem when we signed up for that, and they never removed it? It remains plugged in, ready for action. I'm tempted to unplug it to confirm that it doesn't affect my Internet service. So, the service from outside should not go to a splitter, it should just connect to the cable that goes up the chase to my office, right? As in, I really just need a simple connector/coupler, not a splitter. Upstairs, the current cable terminates in a wall outlet with one connection for the coaxial cable and two for Ethernet ports (only one of which I use). Does a wall unit exist that is also a splitter? Basically, a coaxial out in the back? Or do I cut the cable before it gets to this wall outlet, and split it to the attic bedroom? And again, planning for the future, should I just use the old basement splitter, which will have an extra Out for the day I decide to fish another wire to the 2nd floor TV room? So, the attic splitter would be: - In from the street (actually two coupled cables) - 1 Out to the cable modem - 1 Out to the attic TV - 1 Out open, for future routing to the 2nd floor TV room Thanks so much, --Jonathan...See MoreOld house - Unusual 3-way wiring problem
Comments (12)chezzrob, we must recognize that code wasn't always what it currently is. At some point in history, it was legal to switch the neutral. It was also legal to have individual conductors snaking around the walls and ceilings in all manner of unpredictable directions with twisted, soldered, and taped splices just "hanging around" in there. Think "grandfathered", and remember that we are not required to rewire our houses every time a new edition of NEC comes out. The original poster's installation is legal only because it was legal at the time of installation. You're certainly correct in that it does not, in any way, meet modern code. Regarding 2/3/4-way switching... the standard terminology applied to switches in the USA is for SPST (normal) swithes to be 2-way, SPDT to be 3-way, and straight/swap to be 4-way. ie, a normal single switch is a 2-way, two switches is a 3-way, and three (or more) switches is a 4-way configuration. I have NO IDEA why "they" decided to refer to them this way, but it is what it is. The only answer I've ever been given is that the number refers to the number of terminals on the switch, not counting ground. I don't believe this explanation myself, but it is nonetheless a good way to remember it....See MoreOld 3 wire dryer in new house with 4 wire receptacle
Comments (6)Put the 4 wire receptacle back in just like it was and take the 3 wire receptacle back. Purchase a 4 wire cord for the dryer. The middle terminal on the dryer should have some kind of jumper, either a bare metal strip or a green wire, that gets removed. There should be a place marked where the green wire in the cable goes on the dryer. The black, white and red wires in the cable go to the terminal block. There should be a diagram for all this on the dryer. The standard for dryer wiring is to use 4 wires instead of 3 and it is not code compliant to change back to 3 wire....See Morewiring gfci and grounded outlets in old house
Comments (3)I'm guessing that the install instructions are aimed at the use of NM cable ("Romex") where you need to connect grounds from: * The box * The GFCI * The feed cable * Any "downstream" devices In this case, one generally would use a screw/wire from the box into a wire nut that collected together the cable and the outlet(s). Assuming the insulation on the BX is still in decent shape, I'd use that approach. You can buy short grounding wires, with screws pre-installed in the end which makes the job a little easier if you have more than a handful of boxes to do. I'm not completely sure where the other outlets are, but I'll assume in the same box. In that case, you'd take the hot and neutral to the back of the GFCI and the ground to the wire nut as well. Make sure your wire nut is rated for four #12 conductors (cable, box, GFCI, outlet) -- red or bigger, as I recall. I'm not a licensed electrician, but last I checked there is no Code as to how to install the outlets. My personal choice is to put the ground lug up, so that if something falls against the wall (like a metal tape measure), it hits the ground lug, not the hot. For a sideways install, I put the neutral on top....See Morebtharmy
