Can I do this? Electrical
I know you're going to tell me to do this another way but I don't know
how strongly you're going to say it. I am going away for a few days, and I didnt' expect this. I planned to put a timer on my kitchen ceiling fixture. The one I used to have worked fine but failed, and the one after that failed too (after about 15 years each). The one I bought recently turned out to be no good for CFL's so I just got another one and it wants the neutral wire. Only for the current that it needs to run the internal clock. Not much more than a watch battery puts out, right? All I've got available is the ground wire. How bad is it to use that until I can run a neutral wire?. I already have a 12 or 14 gauge wire running to this box that used to be used for another purpose, but no time before I go away to scope it out. |

Can I do this? Electrical
The neutral and ground wires are often tied together at some pint in the house wiring. Rather than go to all this trouble, why not just have the timer run a table lamp placed on the kitchen table??

It is not legal but it works as long as there is no GFCI in there. I can't say it os a good idea tho. I found a 2 wire occupancy sensor at Lowes that supports CFL and LED so I bet you can find a timer. I suspect there is a resistor or diode array in there that creates enough voltage drop to power the circuitry. |

It definitely won't meet code, but it will work, it won't kill anyone, and it won't burn your house down. Do I recommend it? No. Have I done it? Yes. |

What's amazing is that Amazon has two models, for about $24 and 43, and they will ship it to me tomorrow, meaning today the third if I order it by noon today (which is tomorrow afaic) For $9.98 extra dollars. === Okay, I bought the fancy one. Should come today. Amazing. Even though I'm not in Prime. Were I in Prime it would be free, for over $$35 and $6 for under 35, but non-Prime it's $10 no matter what. They have another model Woods, for $10 that won't come until Saturday, which is still plenty of time. |

Do what you propose, but dont turn on the power until you're ready to leave for your vacation. Right before you leave, spill a gallon of gasoline on your kitchen floor, then toss a match into the gas, lock the door, and leave. The end result will be the same...... The llames will provide a lot of light until the fire dept brings in a bulldozer to remove any dangerous standing walls (If there are any). |

The current on that ground will be on every ground wire in your house. Every metal wallplate and every grounded appliance will have that potential current on it. It is possible that you could touch an appliance and a water faucet at the same time and get zapped. Get yourself some plug in lamp timers. You don't want to create an electrical hazard for your entire household. John Grabowski https://www.MrElectrician.TV |

Buy one of those screw in outlets. You know what I mean, it fits in a normal light socket, but it has slots to plug in. There's probably a name for it but I don't know it.
Put your step ladder under the ceiling light. Put your lamp on the top of your step ladder. Plug your timer into the ceiling outlet and your lamp into the timer. Problem solved. |

(unless you have bonded that EGC to other circuits down stream of the MBJ) In normal installation these are star wired. It still can present a hazard and it is still a 250.6 violation. Whether it would impose the 5ma considered a threat to life would depend on the timer. There used to be a standard in U/L about how much ground current was acceptable from a device like this but it was in the range of 500 micro amps. I believe that has gone away tho. |

I agree it's a violation but the hazard part would require a couple of other faults, wouldn't it? If a ground carries current but is at ground potential, seems like you shouldn't get a shock. If the ground conductor was broken anywhere on the path back to the main panel, all the connected grounds would be hot. But then your light wouldn't work, you'd know you had a missing ground. |

Well, here's my thought process, maybe I'm wrong, but I thought you'd need two faults. You'd need an open EGC, I agree. But remember the way he's wiring it, the lamp current goes back to the neutral, only the timer current goes to ground. The timer only carries 5 mA, so it must be inherently high resistance. So in order for the ground to become hazardous, wouldn't the EGC AND the timer internal resistance have to both fail? What am I missing? |

One of the 3 models on Amazon would work with CFL but only if it met the minimum draw, which was 40 watts (which iirc is 150 watt equivalent, which I think is what I'm using) but I bought one without that requirement. So I bought one that doesn't need a neutral wire after all. They promised it by 9PM if I bought it by noon. I shouldn't be impressed. There have been messenger services that would deliver things quickly for over 100 years. In NYC inthe 70's there were lots of folks on bicycles dellivering financial stuff mostly, and my friend did that with his car. Maybe it's that it's only 10 dollars. |

I just called McGyver and he says I need a foil gum wrapper and two ping pong balls to do this. |

The hazard would still be there with the light turned off. ***Ground at no time should carry any current if it dose it means that some how you ground and neutral; is ****ed up!!! In this case, only the ground from the switch to the panel would carry current - and a very low current. The ground and neutral are "bonded" at the panel so the "ground current" would become "neutral current" at the panel. Not legal, but certainly a very low potential for danger "for someone who knows what they are doing" - particularly as a short term situation. That said, running "an extra wire" is not to code either unless we are talking individual conductors in a conduit, and runs a MUCH higher risk than using the ground for a neutral - particularly for "someone who really does NOT know what he is doing" MUCH better to "ballast" the switch with an incandescent (purely resistive) load or install a switch (timer) that does NOT require a neutral connection.. |

Well, here's my thought process, maybe I'm wrong, but I thought you'd need two faults. You'd need an open EGC, I agree. But remember the way he's wiring it, the lamp current goes back to the neutral, only the timer current goes to ground. The timer only carries 5 mA, so it must be inherently high resistance. So in order for the ground to become hazardous, wouldn't the EGC AND the timer internal resistance have to both fail? What am I missing? Nothing at all. Unless the timer fails there is barely enough "leakage current" to trip a GFCI device, and in order for the ground connections in the house to become "live" the bond between the neutral bus and the ground bus would have to become open. Even a high resistance fault on the bond would not cause a danger unless it was high enough that it could not pass that 5ma of current. (it might take 3ma and leave the other 2ma on the line, depending on your resistance to ground - think "voltage devider".) Without a timer failure the most you would experience with a total bonding failure is a solid tickle. I have actualy held the "neutral" wire from one of those timers in my hand and touched ground without feelng ANYTHING. (I know, no sense, no feeling). |

This is VERY DANGEROUS for those who"don't know what they are doing" Using something like an NE2 bulb would be safe. Using even a 1 watt incandescent COULD be fatal. Again, I stress IF YOU DON"T KNOW WHAT THE HECK YOU ARE TALKING ABOUT DO NOT TRY THIS!!!. And CERTAINLY do NOT advise others. From what you have written here you do NOT know what the heck you are doing.

I am going away for a few days, and I didnt' expect this. I planned to put a timer on my kitchen ceiling fixture. The one I used to have worked fine but failed, and the one after that failed too (after about 15 years each). The one I bought recently turned out to be no good for CFL's so I just got another one and it wants the neutral wire. Only for the current that it needs to run the internal clock. Not much more than a watch battery puts out, right? All I've got available is the ground wire. How bad is it to use that until I can run a neutral wire?. I already have a 12 or 14 gauge wire running to this box that used to be used for another purpose, but no time before I go away to scope it out. I call bull****. In the amount of time you have spent posting here, you could have traced out that apparently unused wire and wired the thing properly. You got that right...... At least 30 years ago, I went to Radio Shack and bought a switch replacement module. I installed it in a room, and using some other items that go with this switch, I could have that light turn on, off, or dim it from a timer, or turn it on and off from a hand held remote, and install more of these switches in other rooms and each one has their own number on the master control and on the remote. Later on, I bought some modules that plug into an outlet, and could turn a lamp, my stereo and other stuff in the home, all from my remote or the master control. I even rigged up around 3000 watts of outdoor xmas lights on these modules and could turn them on and off a block away from home. These modules cost around $15 each, (In the late 1980's) but were well worth the price. I'm sure they have advenced these devices even more by now. So, while this TROLL keeps ****ing and moaning about his plan to burn his mommy's home to the ground using illegal wiring practices, he could have bought some of these modules and had the whole job done by now. But we all know that would end his trolling fun... This TROLL probably dont know which end of an extension cord plugs into an outlet. |

OK if you are not BSing, sorry about that I think it would have taken me five minutes to trace that wire though |
