Electrical problems
So I was on the computer, then all of a sudden I hear BOOM, like an
circuit breaker tripping, and everything went quiet. The computer was off. I took a peek in the electrical panel, but no circuit breakers had tripped. Odd, I thought. But I still didn't have electricity to my computer. I did some investigating, and it seems the bathroom light, and two outlets are dark. That's it. Nothing else. Also, with a voltmeter I checked each circuit breaker. I thought maybe one of them had broken, but was left in the ON position. I took my voltmeter, and checked the voltage of each wire going to the circuit breakers against the neutral. All came up as 120 V. And when I would turn off any one of the circuit breakers, the meter showed 0 V. So it wasn't that. But still, I have no electricity. What could be the issue? Any suggestions? Other oddball ideas that came to my mind was that maybe those particular outlets and lights were connected to my neighbor's circuit. Could this be, or is it totally out of the question? Actually the room where the dead outlets are has one outlet that works. Also the light is on in that room. Weird, I thought all the outlets in a room would be in the same circuit. And the bathroom, which has no light now, has a working outlet also. I'm pretty much at my wits end, and probably will have to get an electrician. But maybe someone would have any experience of a similar situation, before I call one to turn a circuit breaker or twist a knob. |

Oh yeah, as a clarification, I live in a condo, if that wasn't clear
from the post. |

So I was on the computer, then all of a sudden I hear BOOM, like an circuit breaker tripping, and everything went quiet. The computer was off. Some questions that I assume others would want answers to as well: o You said "BOOM", but that's not a sound that circuit breakers normally make. What kind of sound did you actually hear when the power went off? o Any chance that there's a GFCI (ground-fault protected) outlet somewhere in your house that tripped? It's possible that your computer outlets are connected downstream of that outlet, on the "load" side, and that's why the breakers are all on but you don't have power. (It probably shouldn't be wired that way, but it does happen.) o If what you said you did to check your breakers is accurate, in that they all seem to be powered on, then there seem to be 2 possibilities: 1) There's another panel somewhere with more breakers in it, and one of them is tripped. 2) There's been some damage to a circuit, resulting in partial disablement of that circuit. Could be a blown wire inside a junction box, etc. Sounds as if you would do well to get a licensed electrician to look at things. -- The best argument against democracy is a five-minute conversation with the average voter. - Attributed to Winston Churchill |

But maybe someone would have any experience of a similar situation, before I call one to turn a circuit breaker or twist a knob. Circuits for general lighting are rarely done room by room, so it would be perfectly normal to have some lights and outlets working and some not, in the same room. If you heard a pop or "boom" it was probably a short circuit. This should have tripped a breaker, but clearly broke the electric connection somewhere along that circuit. The wiring is daisy chained between lights and outlets on that circuit, so you would be looking for the last live outlet or the first dead outlet on the chain. Not knowing how the chain is run, may require the help of an electrician. I doubt it is a matter of flipping a switch, although it is undoubtedly an easy repair once the location of the problem is found. |

Test other outlets. Find the one that's now off but comes on when you energize the circuit breaker. This is probably the culprit. Call is "SUSPECT." That is, SUSPECT is live, but everything downstream is dead. Wires go from the circuit breaker dot-dot-dot to SUSPECT. From there, wires are SUPPOSED to go to the remaining outlets on the string. Odds are the wires connecting SUSPECT to everything else have a fried connection. If the wires on SUSPECT (or to the next downstream outlet) are connected with stab-in connectors, they've probably made a bad connection, current increased, and the resulting heat melted something in the outlet. Fix is easy. Replace the outlet that's at issue. Don't use the stab-in connections. |

Breakers don't really go boom, it could be a mouse or squirrel eating into the wire. You should check closely in the bathroom. Bathrooms have GFCI receptacles. They have a reset button on them. Other oddball ideas that came to my mind was that maybe those particular outlets and lights were connected to my neighbor's circuit. Could this be, or is it totally out of the question? Could happen, but not likely. You could ask your neighbor if they lost power. |

I didn't think of the outlets being daisy chained, but yeah, if only I knew which way the wire goes, I would know which is the last working outlet... |

Since you have a voltmeter check the hot to ground voltage on the outlets in
case it is a bad neutral. Most likely a bad connection where the wires are backstabbed into the outlets. These are always less reliable than using the screws on the side. If you comfortable doing it, turn off the power to the appropriate outlets and pull them out and look for problems. Remember if the connection feeding and outlet is bad, the outlet may seem to be off but the breaker feeding it still could be on. Always wear sneakers, leather gloves and safety glasses (in case a wire arcs, which can spit hot copper) just to be sure. If there are wire nutted connections these may need to be tightened. Be careful and methodical and you should be able to fix the problem "metspitzer" wrote in message ...

Since I didn't know for sure, I guessed to possible ways of the wire coming in. Meaning, I had two possible last good outlets. So I went to one of them, and it turned out to be a bad connection in that. Actually, it turned out to be a bad connection next to the GFI outlet, which was still working. Who would've known that all the power to my computers was actually going through the bathroom... But in any case, it was a nutted connection, which was loose, so I tightened it, and lo and behold, everything's working again. I guess I didn't need an electrician to turn the screw. Oh yeah, and thanks for the safety tips. I've been shocked enough when I was young and curious and taking everything apart, that I know I don't want that again. |

When you have the electrician come over, you might want to have them fix that situation. I had a customer with a similar situation; their bathroom outlet went out, along with the lights in their garage.

Turned out to be a GFCI outlet in the outside of the garage with all those things wired downstream of it, which made no sense. Actually, it makes perfect sense. Depending upon the date when the house was built, and the electric codes at that time. The most economical (cheap) method of wiring the required GFCI protected outlets was to run the fewest required circuits, to the fewest required GFCI devices. Kitchen circuits, when first required were within 6 foot of the sink, and 20 amp, but most other circuits were general lighting circuits, so it was common to find the required GFCI outlet in the garage, next to the breaker panel feeding the outside outlets and all the bathroom outlets, and if the circuit wasn't to taxed, it may feed a few more lights or outlets It's a very simple fix. -- The best argument against democracy is a five-minute conversation with the average voter. - Attributed to Winston Churchill |
