LV wiring - connection to bare wire
Comments (12)The problem with remote power for LV lighting is the requirement to use "approved methods" for concealed wiring (like anything in the structure). This leads to the use of relatively large cables, since the most common methods use nothing smaller than #14 wire. There are some allowances for LV wiring, but it is VERY power limited (like thermostats and doorbells). High power LV lighting (like that needed for LV lighting) is NOT low power. It is actually easier in many cases to use multiple small power supplies to drive LV lights. This allows the concealed wiring to be 120 VAC wiring (and there are multiple type allowed) while the LV wiring is NOT concealed in the structure (it is often on the bottom of the cabinets). This also greatly reduces the voltage drop in the LV wiring. It is a real issue when even a 10 W lights is puling 0.83 amps @ 12 V, and a 20 W is 1.7 amps. The low voltage also makes even minor drops have a large affect on brightness and color....See Moreconnecting old ceiling wires (5) to new chandelier wires (3)
Comments (3)The old chandelier only had two wires wired into the box and the new chandelier will wire into the same two wires. All the other wires are passing through and should not be messed with. Carefully inspect the two black wires from the new chandelier to see if they are exactly the same. Any difference, (ridges or stripes) means that it will likely be the white wire. Post the photos on here so that everyone can get a look at them....See Moreconnecting new lights to old electrical
Comments (4)I'm going to not-quite-disagree. My safety-oriented side says "fit a box." But my old-house side says "it worked this way for years, and was code compliant when originally installed." That setup probably worked fine. Shame on the previous owner for messing it up by removing the peripheral fixtures - and for fitting that hideous generic central fixture! What was he thinking? There are countless old houses which still have the original K&T for the ceiling lights, and most of them have no boxes at all. They are almost all done as you see here. The wires are enclosed in loom (cambric tubing) for protection and brought right out through the ceiling. The fixture is mounted with screws right into the joist, or even into the lath for fixtures that don't weigh much. This was standard practice and code compliant in those days. Of course it's important to note that very few homes used 100 watt and higher light bulbs in those days. I'm not so sure these installations are as safe when fitted with large incandescent lamps. And (here's my safety side again) you can't be sure that some future owner won't fit large bulbs. Unless, that is, you install fixtures that CAN'T accept large bulbs, such as those using candelabra or intermediate base lamps. ;-) The other problem you'll run into if you dig into this is that once you start to fit boxes, you disturb the wiring. Now you may be looking at having to completely rewire to modern standards, for code reasons and/or practical ones (such as having old insulation flaking off the wires). This may be more than you want to get into, but it's possible that this is where you'll end up anyway. I'd say that before doing anything else, you should first confirm that the wiring is still in reasonably good shape. With the power off, carefully flex the wires a bit. A little dryness in the rubber insulation under the cloth is all right, but if the rubber just flakes off, you have a major problem. If they seem OK, then you can probably install some low-wattage, low heat lighting there. Now, again speaking as an old house fan, I would strongly argue against fitting modern pendant fixtures, if that's what your considering. What you want is something appropriate to the house's period. Try here. Maybe something like this (regrettably this uses A19 lamps which could be upsized too much, but it might give you some idea of what's possible). BTW, I've seen a setup exactly like this in an old house dining room. The house belongs to some friends of ours. The lights fitted, which I think are original, are very small decorative fixtures. The heat produced has to be very low, which as I mentioned above is of some significance here....See MoreNeed HELP installing chandelier - WIRES [PHOTOS]
Comments (15)I faced something similar putting in some track lights and finding a way to feed them. Fortunately for me, there was zero weight on the box since the track attached to the ceiling directly to the joists. But what might help here is that there are boxes available (plastic) for Old Work that attach to the drywall for support. If you have enough slack in the NM (Romex) cable, you can wire inside a new box as Ron said. If the wire is too short, there is a device out there that allows you to splice NM cable end to end without a box. possible box splice kit...See Moregreg_2015
