Electrical Outlet Wiring
I recently began a project where I built a shelf and moved lots of my
computer stuff under the floor and into my basement. Part of it was a mount a power strip with a 15' extension cord onto the ceiling and then use those U shaped nails to neatly get the cord to the electrical socket. I spent a whole day doing it and when I was done, everything was great - except that when I turned off the basement light, the battery backup started beeping. The electric socket is switched... There are two flat cables leading into the socket (which is mounted on the ceiling) and one that comes out. This one goes to a light. That light does NOT go on or off with the switch. It's my intention to open the box and rewire it to not be switched. Before I cut the power, can anyone give me an idea of what I'll see when I open it, and what the best way will be to make it not turn off when the switch is thrown. Maybe one line just happens to pass under the switch, and all I'll have to do is switch between the outlet and the light (I wouldn't mind if the light were switched...) Thanks |

All you have to do is connect your wires to the same wires as the unswitched
light, and you'll have an unswitched outlet. If you want the light to be switched, connect the wires going to the light, to the wires your outlet is currently connected to "Proch" wrote in message . ..

You dont need to even touch the wiring. just remove the screws from the switch plate, stick the thing on the plate and put the screws back. I saw them at Ace Hardware (I think thats where). The cost is under $5 By the way, did you try BOTH of the halves of the DUPLEX outlet? Often half is switched, the other half is not. |

Yeah, but then I wouldn't be able to turn off the lights ;-) Right now I've
got duct tape performing the same task so the kids don't zap my internet connection. Yes, I did try both... I was sure that one was going to stay on, like you suggested, but that wasn't the case. wrote in message ...

Well I was a EE in college, but I know alot more about stuff that runs at 5V
than 120. I'm not worried that I won't be able to figure it out, I'm just looking for a heads up because I can forsee being in the basement with a flashlight trying to figure the whole tihng out while everyone is whining about the power being out...

Depending on the competence of you electrician you could find just about anything under there. I agree, but if he dont know electricity he has to call an electrician and we all know what that costs. He could just put a pull chain on the light too, or another way would be to buy a long extension cord that is a #12 or at least a #14 and use another outlet further away. That's not necessarily the ideal situation, but computers dont use that much power, and the wire gauge is the same as whats in the wall anyhow. It's sort of odd that BOTH halves are switched. Usually it's just one. If this was my problem, I'd just put another dedicated outlet there and leave the old one alone. |

So don't do it in the dark, and don't do it while the family is at home. Run an extension cord of whatever length is needed to get your 1000 watt halogen worklight down there before you turn off the relevant breaker. Then open up the switch and outlet boxes and pull things out so you can see the wires. Don't disconnect anything. Study things until you understand them. Make a drawing of the way things are. Make another drawing of the way things would need to be in order to have a switched light and an unswitched outlet. If you can do that, then make the wiring match drawing number two. If you can't do that, then call an electrician. |

What the heck kind of printer do you use to dim the lights? I have never had that happen. Printers are low power users. It's an older laser printer. When I had it on a 15 amp circuit in an older home, occasionally I did see some fluctuation. The point of my post is that isolating the computer from any other type of interference or possible disruption might be a better choice than trying to tie it in to an existing circuit. It's not clear from the original post what else might be on the circuit. It could also be an older home with outdated and cobbled together wiring. |

The easiest thing to do is just eliminate the switch. Remove the two wires from the switch and splice them together. Put a blank cover over the switch box. |

Sounds like a classic case of both answers being right!
Measured instantaneously, you're correct - the sum of the 3 legs will be zero, but different currents (or 0) will be flowing in each leg. But on an average basis, like if you connected an ammeter, you'd read the same current on all 3. Eric Law "Mark Lloyd" wrote in message ...

Once you open up the boxes and look it will be obvious how to do what
you want to do. Look, draw, think, wire. Preferably in that order. As others have pointed out that doesn't make it the best solution or to code. Aren't you going to end up with lighting and branch circuits on the same breaker? Pretty sure that's against code, you ought to look it up. For that matter, your extension cord across the ceiling is probably wrong. You really ought to run a new circuit from the panel to your computer area, and this is not that hard or expensive to do. |

Lighting circuits /are/ branch circuits. You can't have lighting on your /small appliance branches/, but this sounds like a general lighting branch, and that can have receptacles as well as light fixtures. I definitely agree that the first thing to do is find out what's there...look, draw, think, wire. I'd add a few more thinks, too, at the beginning, especially.

P: There are numerous things that could be in that box, and so you need to find out just what is going on before starting to wire. -You could have one 2-wire cable feeding the box, one 2-wire cable leaving, unswitched, and one 2-wire cable hooked up as a switch loop - out to the switch and back. In this case you'd most likely have just the one cable in the switch box. -You could have one three-wire cable feeding the box, wired to a single branch circuit, with one hot switched and one not, and two 2-wire cables leaving the box, at least one unswitched. In this case, you'd have one 2-wire feed to the switch and one 3-wire from the switch to the ceiling box. In this case, the 3-wire cable woudl have 0v from one hot to the other, 120v from either to the neutral, when the switch was on. Be cautious, however, because with the exact same cables and connections... -You might have one 2-wire cable feeding the box, with one unswitched 2-wire cable leaving the box, and a 3-wire cable running to the switch, acting both as a feed for unswitched outlets downstream, and as a switch loop (the switch would be connected as above, from one hot of the three- wire cable to the other). -You might have a 3-wire Edison circuit feeding the box; two branches with a common neutral, derived from opposite buses at the panel.

GP-
Thank you for taking the time to put that together - this is exactly what I was hoping for... I will open the box tonight or tomorrow and figure everything out before proceeding. Now... would you open the box without cutting the power? Or is this considered dangerous... wrote in message ups.com... TimR wrote: Once you open up the boxes and look it will be obvious how to do what you want to do. Look, draw, think, wire. Preferably in that order. As others have pointed out that doesn't make it the best solution or to code. Aren't you going to end up with lighting and branch circuits on the same breaker? Pretty sure that's against code, you ought to look it up. For that matter, your extension cord across the ceiling is probably wrong. You really ought to run a new circuit from the panel to your computer area, and this is not that hard or expensive to do. Tim: What do you mean, branch and lighting? Lighting circuits /are/ branch circuits. You can't have lighting on your /small appliance branches/, but this sounds like a general lighting branch, and that can have receptacles as well as light fixtures. I definitely agree that the first thing to do is find out what's there...look, draw, think, wire. I'd add a few more thinks, too, at the beginning, especially.

P: There are numerous things that could be in that box, and so you need to find out just what is going on before starting to wire. -You could have one 2-wire cable feeding the box, one 2-wire cable leaving, unswitched, and one 2-wire cable hooked up as a switch loop - out to the switch and back. In this case you'd most likely have just the one cable in the switch box. -You could have one three-wire cable feeding the box, wired to a single branch circuit, with one hot switched and one not, and two 2-wire cables leaving the box, at least one unswitched. In this case, you'd have one 2-wire feed to the switch and one 3-wire from the switch to the ceiling box. In this case, the 3-wire cable woudl have 0v from one hot to the other, 120v from either to the neutral, when the switch was on. Be cautious, however, because with the exact same cables and connections... -You might have one 2-wire cable feeding the box, with one unswitched 2-wire cable leaving the box, and a 3-wire cable running to the switch, acting both as a feed for unswitched outlets downstream, and as a switch loop (the switch would be connected as above, from one hot of the three- wire cable to the other). -You might have a 3-wire Edison circuit feeding the box; two branches with a common neutral, derived from opposite buses at the panel.

Well that's true but you're probably not going to see anything useful either.
Most boxes are such a rat's nest that it's hard to see what's going on even with the switch/outlet pulled out! Eric "Proch" wrote in message . ..

Yes, but are those stapled wires which carry line voltage what you described as "extension cords" or are they Romex or other approved permanent wiring material, and do they have plugs on their ends or do they go into traditional electrical boxes? I couldn't hurt to check it out with your town's electrical inspector, could it? But, do what you want, it's your house, not mine. And as I said before I think the direct risks are minimal, it's just thinking about the posible code violation which got me going.

wrote: Sounds like a classic case of both answers being right! Measured instantaneously, you're correct - the sum of the 3 legs will be zero, but different currents (or 0) will be flowing in each leg. It doesn't have to be instantaneous for the currents to be unequal. There is a difference in phase. My "problem" was in failing to know that one of the important characteristics (phase) was supposed to be ignored. BTW, in a different class I had just been taught about phase, and the way the phase of the voltage and the phase of the current can be affected by components in the circuit (power factor). Obviously, 120V @ 0 degrees is NOT the same thing as 120V @ 120 degrees. But on an average basis, like if you connected an ammeter, you'd read the same current on all 3. Since ammeters don't show phase. Phase is still real, as you should know. Eric Law "Mark Lloyd" wrote in message ... I was studying digital electronics in college, but did once take an elective course in NEC. I remember getting one test question "wrong", in one of those cases where you get penalized for knowing something you aren't expected to. The question was about a 3-phase wye-connected motor, and asked True or False: the current in each leg is the same. The supposed "correct" answer was True, although I knew that was impossible. One of things they taught in electronics was that the sum of the currents in a node is always zero (electrons are flowing FROM somewhere TO somewhere). The currents could never be equal unless they were all zero. -- 67 days until the winter solstice celebration Mark Lloyd http://notstupid.laughingsquid.com "God was invented by man for a reason, that reason is no longer applicable." -- 67 days until the winter solstice celebration Mark Lloyd http://notstupid.laughingsquid.com "God was invented by man for a reason, that reason is no longer applicable." |

Now... would you open the box without cutting the power? Or is this considered dangerous... P: I always start by turning the power off, then check with my neon voltage tester to make sure it actually is off. (Actually, I usually check before turning the power off, too, to make sure the switch is on. Otherwise you can get a false safe reading, and then somebody comes by and flips the switch ON...). If possible, I check before opening a box (by checking across a socket or receptacle), but in any case I always check after opening the box. Even if I have turned off the breaker or removed the fuse, I assume the wiring could be live, until I have verified that it isn't by checking it. You never know what you are going to find in an old system. Generally, I check from hot to neutral, then from all wires to a known good ground, after turning off the power. Preferably, I check at exposed terminals. If that's not possible, I unscrew wirenuts. This needs some caution, since wires aren't always twisted together and may spring apart when the nut is removed. After I am sure the box is dead, I see what is going on in the box. /ALWAYS leaving the wires connected/, I unwind the rat's nest and spread the connected wires apart, and then write down how everything is arranged, what is connected to what, etc. I may tag the wires with pieces of tape. Only after writing down what I start with do I start disconnecting wires. Once everything is disconnected and safely spaced out, if I don't already know which wires are the feed, and I can't find out by visual tracing or continuity-testing the circuit, I may turn the power back on briefly to check for voltage at the various wires. Be careful when doing this, because you are checking a live circuit, and don't want to be part of it, of course. As soon as the tests are done, shut off the power again, and check to verify it's off. This is one of the few cases in which I will allow power to an opened box. If possible, I try to avoid it, but even in some cases when I think I know just what is going on, I'll double-check this way, just to be safe. The most important thing is to know what you are doing, and I really can't guarantee that across here. I can only explain how I do it. It's up to you to be sure that the job is done safely, and if you aren't sure you can do that, you shouldn't do it. Usenet just isn't enough. G P |
